I'm a newbie here, and not sure if this is the best forum for my question (the alternative being the DVD forum), but I'll try here first!
I transferred an analogue videotape to a mpeg2 (.mpg) file (via Winfast PVR), and that file plays perfectly in any player application. I spilt the file into 6 clips (also .mpg files) using VideoStudio 7 SE DVD. No problem there either (apart from a few editing bugs in VS7!) - all the clips still play perfectly in any application. Then I went to Share-->DVD and imported all 6 clips, added titles etc, previewed the result in the preview window (played perfectly), and finally burned it to a DVD-R. I ticked the box that said "Don't convert compatible files", but VS7 still spent ages 'converting source files' (or whatever it said) before starting to burn the DVD.
Problem is, the DVD sound (on all clips) is about 5 seconds later than the corresponding video. This occurs whether I play it on the PC (several players tried), or on my stand-alone Pioneer DVD/SACD/DVD-A player. On the second attempt, I asked the Share application to write its files to my HDD as well as burn the DVD. I later played some of those 'converted' clip files, and they too had the delayed audio. So the problem appears (to me) to be in the conversion process. What am I doing wrong?
As mentioned above, all the clip files were .mpg, with sizes ranging from 220-460MB. My DVD-RW drive is a Lite-On LDW-451S (with the latest firmware installed), but I don't think it's the problem, as the converted files on my HDD also play incorrectly.
Being in Australia, my output format is PAL. My PC is a 3GHz P4 running Win2000 Pro, and all my video work (including temp files) takes place on a 360GB NTFS partition. Let me know if you need more info. Any help would be appreciated.

Can you right click on one of the captured mpegs within VS and copy its properties here please. By the sound of it, you may not be capturing mpeg-2s which are DVD-compliant and they are being converted in the burning process -- which is a bit of a no-no in its own right.
What is more, it sounds as though they are being rendered with Smart Render enabled. This has been known with earlier versions of VS to cause out of sync audio and video.

Ken,
Thanks for your quick response! You can see I'm a real novice at creating DVDs (this was my first attempt) - I didn't know there were different 'flavours' of mpeg2 for DVD and other uses. I've sent you the clip properties directly to your eddress, as I don't know how to insert/attach graphics (screen dump) to a message here.
When I captured the video with Winfast PVR (first time I've done that, too), there was a bewildering range of options for the recording format. 'Mpeg2 optimum' was the default, and when I checked the specs of another option labelled 'DVD', it looked identical, so I stayed with the default. Looks like that might have been my first mistake.
Unfortunately I won't get another chance before Boxing Day to try the transfer from tape again, but, depending on your further advice, I will try it again then with 'DVD' selected as the recording format, and repeat the (tedious) editing to try burning a DVD once more. Or maybe I'll get game and see if I can use VS7 as the capture application instead of Winfast PVR - any tricks to this?
I think I had Smart render turned off, but can't be sure - I'll check next time I attempt this DVD.

What card did Winfast PVR come with? In my case, it was with a Winfast card (DV2000) but it also comes with Hauppage cards, and they have some peculiarities. I would have to defer to some of my other colleagues on this Board on that. But with my card, I just used the Winfast software to do the captures. If I recall correctly, I also just used the Optimum setting as well. That always worked and I was usually pretty pleased with the captured video quality too...
Did you do any other editing or did you just split the original capture into the 6 smaller files? When you split them, what did you do then: for example, did you click on 'Save Trimmed Video' each time you split off a new file? If you did that, you would then have noticed that a new video icon, with a new Ulead gobbledegook name would have appeared in the Library pane. You should have noted each of their names.
If you didn't 'Save Trimmed Video' and note down the names, can you also confirm what you did then when you said you went to "Share > DVD". You see, that jumps an important element in the middle. Ideally, if you didn't 'Save Trimmed Video' above, you should have gone Share > Create Video File > DVD and NOT used Smart Render. You would have had to do this 6 times. That would create 6 new DVD-compliant mpeg-2s. Unfortunately, there would have been a small amount of degradation in the quality since you were in effect recoding an mpeg-2 file, which is a lossy format. But if the original properties were indeed Optimum, the loss should not have been visible to the naked eye that first time round.
Instead, I suspect you used Share > Create Disc > DVD. That would have used your project file (.VSP) in the burning module, and this is probably where the sync error crept in. Theoretically, it is possible -- and some people do so successfully. But in practice, it causes a lot of people a lot of grief as it means VS is converting the project to DVD-compliant mpeg-2s during the burning process, as well as performing all the other complex elements of a burn, and all on the fly.
My own preference, if you did not intend to do more editing, would be to use the 'Saved Trimmed Video' route. After the new files had been Saved, I would have then closed the project. Then with an empty timeline, I would have selected Share > Create Disc > DVD, and inserted the new files whose names you would have noted in the Library pane. If they started life as Optimum DVD-compatible files, they would not need converting any further in the burning module.
Or else, if I did it the longer way and had first gone to Share > Create Video File > DVD six times, then I would then, with an empty timeline, have gone to Share > Create Disc > DVD, inserted those 6 new mpeg-2s, and burned. Again, because you specifically created them as DVD-compliant, no further encoding would be necessary in the burning module.
P.S. At the time of posting this, nearly two hours after your last post, I have still not received the email...

Ken,
Thanks for your further input.
My capture card is the Winfast TV2000XP Model 1.
My only editing was to split the file into 6 parts (deleting the TV ads!), and I clicked 'Save Trimmed Video' each time, nominating the directory and filename to save the trimmed sections.
When I went to Share->DVD, I initially re-loaded my project, but quickly realised that it was going to re-join my 6 parts into a single video stream, which is not what I wanted (I wanted each segment as a selectable clip on the DVD). So I deleted the project (in Share) and added the individual video clips I had previously saved after trimming.
As for Share 'converting the project to DVD-compliant mpeg-2s during the burning process, as well as performing all the other complex elements of a burn, and all on the fly', I don't think this is what happens. The Share application first said it was converting ('rendering'?) the files (with a progress indicator), and this took a long time (I didn't sit around and watch it) - maybe 20 minutes or more - before the DVD drive was accessed and burning started. At this point Share said something like 'burning project' (sorry I didn't note down the messages) with a new (re-started) progress indicator. So I'm guessing it does the rendering first (to temporary files), and only then copies them to the DVD drive. As I mentioned in the first post, I found these temporary files after the second attempt (when I told it to also create DVD files on my HDD), and they were 'bad' (delayed audio) just like the resulting DVD.
So it appears to me that I have pretty much followed (preceded!) your advice, but with unacceptable results. Unless some other approach is suggested, I shall try recapturing using Winfast's 'DVD' selection, and then follow the route you suggest (as before) to see if the result is any different.

Render your MPEG2 files in order to create a new video file using the 'same as project properties' setting and make sure that the 'Smart Render' option is disabled.
If your MPEG2 files are technically corrupt, then using 'Smart Render' will place your audio way out of sync. You can render corrupt MPEG2 files perfectly within video studio if 'Smart Render' is disabled...I've been doing that for years.

Terry,
I tried your suggestion, but the resulting file was still ~5 seconds out of sync. Perhaps I'm not correctly understanding your directions...
After loading just one of my clips into VS7, I went straight to Share and selected 'Create Video File/Same as Project Settings'. Then I un-ticked the 'Perform SmartRender' box, named the output file and clicked 'OK'. Is that what you were suggesting, or is there some other way I should have done it?
