Advertisements CyberLink Video/SP Decoder That's what it says trying to play a TIVO file. I do hear AUDIO tho. Under Tools-Options-DVD-Advanced it says... Main Concept MPEG Demultiplexer I have installed MY DVD, Roxio Cine Player, CyberLink DVD, etc. I should have codecs out the butt now. They suggested at the TIVO forums to try Tools-Options-Performance Tab-Advanced... and mess with those settings. I saw this in another thread they replied too over the same problem. I tried this alreayd too but I went ahead and tried it again. Click one or the other "Video Mix Renderer" setting, then neither. Messed with all the other stuff, tried turning all the stuff off. Nothing works. Tried playing some other avi files ok. I also tried rolling WMP back to an earlier version then reinstalling WMP 11. Only other thing I can think of is to try and remove WMP all the way if I can.
