Wait a sec.
For OGM+ subtitles look at this:http://forum.bsplayer.com/bspforum/viewtopic.php?t=393
FFdshow is doing fine on my WinXP and on all others, AFAIK. Maybe there is a noticable playback quality decrease with XVid compared to Nic's postprocessing filter (http://nic.dnsalias.com/). But that should be all.
There are two ways for uninstalling codecs/ filters: If it was installed with an installation routine ->control panel -> Software -> uninstall.
Or look under control panel -> System -> device manager -> audio + videocodecs, double click, tab properties, remove
Or for filters (.ax): regsvr32.exe /u [filtername.ax] in command line simply to unregister, it's not gone, you can register it again without (/u).
It looks like you need a fresh install of your player and codecs: latest!

BTW, over at Doom9 DJ BoBo ( horrible nick, em!?) solved my problem with capturing image: you have to turn on overlay mode 1.

As brave as a student can me: Why, I have to ask. What makes the difference between 1 and 2 ?
