I downloaded a movie and played it back in Media Player 9, it had sound but no picture. So I tried playing it in Divx Player, but it didn't work at all. I got the following error message..... Video Data: FOURCC code "XVID" So the question is, what is XVID (apart from being DIVX backwards). And what codecs do I need? **EDIT** sorry, I just found out that I needed the XVID codec, which I have installed, and it works.
