Spinning ball when browsing Xvid videos..

Hey guys, I'm afraid I have abit of a difficult one with not much to go on. 😟

I have my Mac Mini G4 hooked up to my standard def tv via the Composite/S-Video adapter and running iTheater on it to play back Xvid movies, the problem is whenever I'm browsing to find a video inside of iTheater, my Mac will freeze up, with a spinning ball going continuously. The cpu fan will go into turbo mode, but I think it eventually gets over it after a few minutes and unfreezes (thaws? :p).

Ok, so, here are the details
- 10.4.11
- iTheater 0.2.0
- DivX 6.7

Now, I've been watching movies fine in DivX Player, and Quicktime appears to play them as well, I haven't played for too long since QuickTime won't do full screen.(I think iTheater uses it as a backend)

It will freeze whenever I highlight a Xvid video (but not always, sometimes I can highlight a few no worries), which should be when it gets a thumbnail of the video, if I'm correct, but never does. It seems to affect videos in the Movies folder and via my Samba share on a windows box, both wirelessly and wired.

The problem doesn't appear to happen when connected to my 17" computer LCD.

The problem used to happen with MediaCentral many months ago, but I eventually rage quit and dumped my Mac in a cupboard. MediaCentral if I remember correctly would freeze when browsing videos even though the software doesn't generate thumbnails.

I've tested the RAM using the Apple Hardware test and Rember, and it passed both.

So, that leaves me with the following theories (I think),
- Codec issue
- Something to do with my settings for displaying it on the tv which are causing it to hang (they're default, and its a PAL tv)
- Hardware issue.


Anyone able to help? 😟
