I've recently run into two XviD files that would not play correctly on my Philips DVD player, even though they looked fine on my PC.
My usual method is to burn a DVD using Deep Burner in the CD File mode (No multisession), and select the file from the player's menu.
After snagging all the episodes of the "Tin Man" SciFi series, I whipped up a DVD and enjoyed two out of the three parts. The third file had blocky video.
I have already reencoded and reburned the DVD, so I'm not going to ask how to fix the problem. Rather, I want to be able to identify future problems before burning the disk.
I thought the problem might be GMC/QPEL related, as that is a known limitation with the Philips player. But, after squeezing the info out of the offending file (with GSpot), I see that GMC and QPEL are not being used.
The only significant difference between the two good files and the one bad file is the codec:
Good codec = XviD 1.1.2 Final
Bad codec = XviD ISO MPEG-4
The same (blocky video) symptoms showed up again with a file that was encoded using "XviD 1.1.0 Beta 2".
Does anyone know of any problems with these codecs as releated to the Philips player? Is there another file aspect that could be the cause?
Here is a table showing the file particulars according to GSpot. Blank entries and Audio information were removed.

The following things can be problems on any DVD player that supports Divx/Xvid:
1) GMC (rarely supported and if it is supported, ONLY for 1 warp point, despite claims to support 3 warp points)
2) QPel (Quarter Pixel)
3) Packed bit stream (the Philips DVP-642 absolutely will NOT play these files, if that's your player model. Fix with MPEG4Modifier.)
4) Resolutions greater than 720x576
5) Video bit rates above 2000 Kbps. In fact, some chips will require your video bit rate to be as low as 1400 Kbps or maybe less if your audio is anything other than MP3).
File sizes larger than 2 GB can also have playback problems. Philips DVD players typically don't have issues with VBR MP3 playback, although other player may.
If your audio is AAC, that MIGHT be a problem, although usually Philips players just play these files silently rather than not at all. If your files are not in an AVI container, this can also be a big problem. Some Philips players won't touch MP4 containers. Others will.
I'd look for file sizes larger than 2 GB and packed bit stream as the likely causes of your issues. Also check to see if your files are in MP4 containers (most likely their names will end in .MP4). Whatever your problem is, it is definitely NOT a codec issue. -
My only thought (after reading a similar post earlier today) would be B-VOP. The other user found information stating players have problems with files containing more than a single B-VOP. I don't know if it is true or not, just something for you to investigate.

Using Quantisation Matrices other than the standard 2 produces AVIs that won't play well in ESS chipset DVD/MPEG-4 players. You get these colored blocks which may be what you experienced.
