Etech,
I made short clips of same project both in WMV-HD (available at Azureus : titeled sumer dream ) and DivX-HD to compare
WMV--HD nice smooth and clean
Div X-HD the imported music of the same video played few seconds longer than the film;
Now I use WMV to share video

de-interlacing is combining the two upper and lower frames back into a single image. Think of inserting the odd and even lines of the picture in the original order.

Analog TVs need interlaced contents. Digital TVs (or computers) need progressive (or frame-based) movies, but as said just before, the software usually takes care of it.

Not 100% exact with movements because the two fields were not taken at the same time.

toni1,
I bought the same consumer playback device that JcHunter was using called a "Linkplayer2". I think it has been upgraded to a newer name and plays the new divx menued dvd's along with other new features.
I paid $249.00 US for mine. I think the newer ones are $299.00, depends if you buy the one that has dvi output or component. Mine is component output.
I know you projector is 1280x720. My linkplayer2 takes the original hd-mpeg2 video and when connected at 1280x720p the linkplayer2 converts the fields to progressive format which then drives the 1280x720p display. The linkplayer2 converts the video to all the Display Modes upto 1080i. The PlayStation3 will go upto 1080p on a hdmi connector. I've found that the linkplayer2 somewhat better versus the PS3 when playing back HD-Video with very fast motion. The PS3 has more features though for viewing the HD-Videos. Still expensive though.
On the LinkPlayer2 the videos play nice & smooth. Also playsback HD-WMV, HD-Divx, music files etc. Also comes with a small utility and you can play HD compressed videos from a network.

Connecting a computer to a HDTV can be awkward with the cabling and all. Usually I have the linkplayer connected to my HDTV Monitor, save the HD-WMV or HD-Divx files on my local drive. Through the linkplayers2 server utility program the unit plays the HD compressed videos across the local network from your harddisk. You can also connect USB drives to it, DVD's data or dvd-video. So I can get 40minutes on a dual-layer dvd.
The linkplayer2 isn't expensive compared to the other units made
Panasonic & Sony playback devices.

The linkplayer2 is similar to a dvd player, also portable, I've taken it other places & connected it up to view some videos on HDTV's.
Most people that purchase a HD-Cam at the time of purchase don't consider the fact they need an approved HD playback device. At the time I purchased my hd-cam I didn't think playback would be to much of a problem. Well it was, experience is still the best teacher.
Just think, in 4-5 years all this equipment will be 1/2 the price.

Yes, but by then we'll all have moved on the next latest & greatest invention.

Not all Lab:

I just bought a brand new television. 4:3 29-inch slim-line CRT.
I guess it will last about ? 10 years ? (Crosses fingers)

Hi etech6355
How do you burn you dvd for playback on LinkPlayer2 are these data burned type or do you have to do a video type dvd
If its a data type dvd and you have let's say 2 video files on it how do you select 1st or 2nd file ; is this done through the player panel or are the files displayed on TV ?

I was actually referring to when we'll be able to record in SooperDooper Hi-Def 3D, then you'll need a new SooperDooper HD3D TV!

Toni1,
You just write the files to dvd as data files. The linkplayer2 uses a menu system that's displayed on the TV, then you use the remote control to navigate.
Video extensions it plays are mpg, m2t, wmv, divx.

To play HD-Mpeg2 in PS(Program Stream) format the maximum setting is 18MBS Variable bit Rate.
To play HD-Mpeg2 in TS(Transport Stream) format the maximum setting is 25MBS Constant or Variable bit Rate. (Original format on the tape).
To play HD-WMV format the maximum setting is 8MBS. HD-WMV is impressive.
To play HD-Divx the maximum setting is 8MBS Variable bit Rate. HD-Divx is impressive.

VS captures in PS (program stream) so you have to re-encode to 18VBR.
You could use HDVSplit to capture straight TS from the cam to the harddisk or external drive & immediately play them back on the linkplayer2. VS10 will also convert the HDVSplit captured files to PS format so it can edit them if need be.

In 10 years they won't be transmitting interlaced video anymore.

With all this fast change going on, I'm just waiting for one of those Halogram TV's. You know like in Star Wars, where your TV is just displayed in the middle of the room...

Or HD-WMV format at 8MBS.

What is better To play HD-Mpeg2 in PS(Program Stream) 18MBS Variable bit Rate. Or HD-WMV format at 8MBS.

My preference is staying with the mpeg2 format. Always works and is the best quality. HD-WMV doesn't support interlaced video so the conversion converts the video to frame-based. Same with HD-Divx if you de-interlace the video, but you don't have to de-interlace divx, divx supports interlaced, but I've found the files only playback correctly on a hd-divx certified player. My computer doesn't like playing them. Conversions to HD-WMV are tricky and time-consuming. I prefer Interlaced HD-Divx over HD-WMV for now because de-interlaced HD-WMV isn't smooth. There are methods to correct this, I haven't had the time. I also have the hardware device LP2 that can playback the interlaced hd-divx files.

This thread is now 4 pages long. Looking at your original post it appears to me you took HD-Mpeg2 Upper_Field_First and down sampled it to SD-Mpeg2 Lower_Field_First thus reversing the fields. So that would explain the video being jumpy. Dvd player lockups could be many things so I would re-render again this time to Upper_Field_First and burn at 4X. I would burn a DVD-R disk for best compatibility.

Hello etech6355
It annoys me to have to down sample to 18 MBS for Linkplayer2, its so much time consuming to render:
Is there a new model that will take 25MBS
Second: Did you try to connect an external hard drive through usb, because that feature is interesting for me since I use big external hard drives to stock my videos

For voice synchronising problem , the sequence of work is UFF hd-mpeg to frame based HD-mpeg2 to Pal progressive and its in the last step that synchronising problem happened (will have a closer look at this file)

The one that I finished as LFF didn't have this problem

Have you considered using hard drive caddies instead?
