Trouble with video output quality on latter part of DVD disc

[johncal]

I have DVD Movie Factory 4 which came bundled with my pioneer DVR-R110D burner and am using panasonic dvd-r 8x discs. I have burned other discs without problem. My source files are either mpeg or Divx. I have burned the disc twice - once at 8x and once at 4x - no errors were reported. However, Both of the DVDs created have a problem with clips on the latter half in which the quality pulses - between good and then fuzzy every few seconds- it happens on both Divx source clips and Mpegs. I tested the source files and viewed the movie factory preview before the burn and they did not have this problem.

Anyone have any idea as to what may be causing this? Any help would be greatly appreciated.

DivX also XVid and MPEG4 are highly compressed formats suitable for sharing video over the internet. Very few Standalone DVD players will accept these formats though one or two have slowly begun to appear on the market.

The DVD format will only use MPEG2 to create its VOB files. Anything other than a DVD compliant MPEG 2 (in terms of screen size, bit rate, audio format) will have to be converted to that format first. this is why some videos appear to turn into DVD's very quickly but others take hours.

Regarding the burn speed. I have a 16 speed burner and I use 8x discs.
However..... After testing discs in several standalone DVD players (Friends & family) I NEVER burn faster than 4x. Although the DVD will be created at the higher speeds it suffers from signal weakness.

One of our forum members (I think it was Devil ) examined the discs under a special microscope and confirmed the pits in the CD are not as deep when burned at higher speeds. On playback some DVD's are more sensitive to this phenomenon than others and refuse to play the discs back either correctly or not at all.

Thanks for the reply Steve. But do you have any idea why the quality fades in and out every few seconds on the last half of the disc? Some of the source files were mpeg others divx. Could the cause be that I used a 16.9 output format?

If it isn't one of the previously mentioned problems then it may be the discs themselves. I buy mine in bulk a few hundred at a time. You gert the odd few discs that have minor faults even though the resdt of the batch is OK.

Take one of the "problematic" discs and examine the surface by tilting it about and looking at the reflective area. Also check for fingermarks etc.

Burning to 16.9 or 4.3 will make no difference.

If you provide the brand of the media it might be helpful.

Some disks have poor quality so when you play the disk you might see jumpy video on the last half of the disk.

Also Pioneer DVR-110/DVR-A10 might not compatible with some media brands and it might need some firmware update to solve the issue. You might need to contact Pioneer for this but it should be the last step to check because firmware update might damage your burner if not updated successfully.

Check the DVD Player Compatibility List to know what disk might be suitable for your DVD player. And check the DVD Writer List to know what disk might be suitable for your burner.

Hope this helps.

Thanks for the help. I'll check the discs. As far as the media and the burner are concerned, I already had successfully updated the firmware and I am using panasonic 8x dvd-r that is recommended by pioneer. I burned a similar project using AVS and it didn't run into the same issue although there are other bugs in that program when you edit chapters.

Hi,
Your videos are in digital format on the dvd.
If there's something wrong with the dvd's or the burn you will see "Blocks" of Rectangles on the screen (data errors). Not fuzzy wuzzy stuffee's.

Most probable cause of this is the conversion from divx to mpeg.
Your source files are probably having a hard time converting in that point of the video.
Try a different video program to convert the files to dvd.
