Avi file won't play on DVD

[Booooom]

Hey,
I have a DVD which is able to play DivX and XviD files (tested many times). Recently, I have encountered several XviD files which my DVD was unable to play.
At first I thought it was because the bitrate it too high, as it was 1887 kbps, so I recompressed it using VirtualDubMod into a XviD 860 kbps to no avail.
My DVD is able to play XviD with much higher bitrate (1100 e.g.) I tested it myself.

Does anyone have any suggestion where to look for an answer? things to try?

Thanks.

Wow, afterdawn, doom9 and here. You might want to check back on your other posts.

I still think the most likely answer is that it is larger than 720x576, but then you didn't really post any of the specs.

lol yeah, do you know any other good forums?
You were right on the money. The avi in question is 960x528 and I feel stupid for not noticing that.
So what exactly can I do to change the resolution?

I will thank you on Afterdawn as well

Use the Resize filter in VirtualDubMod. Lanczos3 will give the best results.

Problem with resizing in VDubMod is that even with a high quality resizer like that you still have to convert to RGB24.

Thanks pps for your replies...
Why would I need convert to RGB24? (sorry for the question, I have never butchered an AVI before)

VirtualDub's filters only work in the RGB colorspace. The Xvid contents is in the YUV colorspace reduced to YV12 (or something similar). To use VirtualDub's resizing filter you'll have to enable Video Full Processing Mode. That will convert the XVID YV12 data to RGB, resize, and then the RGB will be converted back to YV12 for Xvid compression. The RGB/YV12 conversions will lose a little precision and slightly blur the colors.

You could use AVISynth to reduce the frame size without converting to RGB and get slightly better results (and slightly faster since you'll avoid the YV12/RGB conversions). I doubt you'll really see any difference.
