AniDB

Everytime I wanna play one of my fansubs, it keeps telling me I'm performing an illegal instruction.

Is this due to the fact I have Spybot and Bulldog on my CPU?
Or am I downloading wrong.

BTW, the file was Naruto 1 and FLCL 1 and both came up to Illegal Instruction even with Oggsplitter and all the other codecs. I don't know what to do...

Since the problem also occurs with Naruto, it doesn't look like a problem with ogm.

• Compare some of the problematic files to the checksums listed. (Using AniDB-o-Matic or HashCalc or just some simple CRC-checker)
  That way, you can make sure your files are not corrupted.
• Try another player, e.g. BSPlayer, MPC, ZoomPlayer.
• Use GSpot and let it attempt to "render" the problematic files. That way, you can find out what they have in common (e.g. all are XviD).

(For links to the programs: see the "How to play the files..."-sticky.)

Btw.: I have no idea what "Bulldog" is, so I don't know whether it may cause trouble or not, but I doubt it.

You might want to try to uninstall both XviD and the Ogg-codec and then reinstall them.
I got a similar problem when I had DivX 4.12 installed and it conflicted with the Ogg-codec. I also encountered a similar problem with an older XviD build which clashed with the Ogg-codec. An uninstall and reinstall solved that though.
If that still doesn`t work, let ffdshow cover the XviD codec for a change - it might help.
