Multiplexing non-standard mpeg2

[Hironimo]

Hi there

I converted some avi files to mpeg using cce, which gives me an mpv and an mpa file. The resolution is something like 576x320 (16/9-ish).
The video plays in the correct aspect ratio in the original mpv but when I mux audio and video it plays it as 4:3.

I am searhing for a multiplexer where I can set the aspect ratio too.
Can you help me?

The aspect ratio information is stored in the .mpv, so muxing won't (or shouldn't) affect the AR at all. It is rather strange that the .mpv and the muxed version look different. Perhaps your player is using different decoders for each file? If it's using a DVD decoder filter, it may only support 4:3 and 16:9 because that's all that's allowed on DVDs. (To look correct, yours should be played at 1:1 like the original AVI.)

If your goal is to make a DVD of this movie, you'll have to resize it to look correct at 4:3 or 16:9. Are you making a PAL DVD or an NTSC DVD?
