somewhat strange. I did my AVI file, two vorbis audio streams and two SRT subtitle streams. they all play fine, the problem appears when muxing to OGM, with OggMux 0.9.4.1 or VDubMod 1.4.13.1.
The avi file by itself plays perfectly, as it was intended though. but when I try to play the OGM file, all players (BsPlayer, ZoomPlayer, MPlayerClassic and WMP6) understand that the video has a resolution of 1024x576 instead of the 512x208 that the original AVI has. GSpot says that the OGM file has 512x208 and the file is player with its correct video size on MPlayer (Linux). The problem shows using the DivX Decoder Filter and FFDSHOW (latest alpha version).
FFDSHOW Info (and here´s the funny thing) also says that it is a 512x208 video but the player displays a 1024x576 one (black bars included). well, and all the players hung at a random point of the file.
The software:
DivX 5.02, GKnot 0.27, VDUB 1.4.13, Subrip 1.14, BeSweet 1.4, OggDS 0.993, BSPlayer 0.86b495, WMPlayer6...

You can find here samples of OGM (http://www.terra.es/personal9/dvdbackup-esp/samples/Sample1.zip) and AVI (http://www.terra.es/personal9/dvdbackup-esp/samples/Sample2.zip) files.

If you're using vobsub, probably the problem is there.

I'll explain you how I found the problem on my system, maybe it could help you if it's not the same problem: I checked the sample and the same problem appeared; then opened the ogm in graphedit, and tried deleting the filters involved. Vobsub appeared in the graph, and once deleted the video played nice.

OK, now the solution: vobsub has a config dialog (the vobsub icon should appear in the task bar when opening the file and double clicking brings it, if not the case, check the WMP properties dialog or something else. On the "general", setting Vertical padding to original height and Resolution to original resolution should solve the problem.

If vobsub is not in the graph and the Tobias' subtitle mixer is, maybe that's the problem (it has also a config dialog to tweak the resolution but I don't remember is affects the final video resolution or only modifies the subtitle aspect ratio).

I hope it helps.

I knew that the vobsub stuff was the problem just when reading your reply, and it was. I tried what you proposed and it worked like it should. I cannot understand why are these values set by default and, more important, how could I forgot not to install vobsub when installing gknot. thank you very much.
