I'll give it a try when I wake up...

I've tried the TV out kext but I don't think it did anything or else I don't understand how to activate the svideo port in os x on my video card... as for the divx video I don't have one that I can test out

I am having this problem as well. Can anyone provide a link to download the working drivers from the dead rapidshare link in this thread?

I'd much appreciate it too.
If it's not possible to share kexts, then I hope someone could share with manual like what and where should I change to make my video work correctly.

By the way, naquaada, where you able to make dual-monitor work?

I'm not using the X1600 anymore, I've switched all my 4 computers to an HD2600XT.
