Re: MPEG-4 playback problems

I do actually, I just downloaded and installed 3ivx_d4_45_osx.dmg. I've run the uninstaller script but that didn't help. Do you know how I can manually remove them ? Why should this stop mpeg-4 from working ?

It was actually just a guess, I'm not sure that has anything to do with it, but it could. 3ivx registers itself so that it takes over decoding of all MPEG-4 - trumping Apple's MPEG-4 decoder... at least that's how I've observed it. My assumption was that while this may work fine for most video (and it does), that 3ivx may well not handle MPEG-4-encoded VR properly, for whatever reason.


Can you download one of the VR's in question? If so, open it in Quicktime Player - what info is showing for the video track in Movie Info? If it shows the 3ivx codec, that may be the culprit.

As for how to fix it... removing the component and then restarting the Quicktime app you're using should work. If not, you may have to restart, though that shouldn't be necessary (should it? or is that only true for adding components?).
