Checking on previous threads, I noticed the Quad 99 kit (cd-p and stereo power amp) and I wondered if there were any problems with compatibilty with regular DVD players (Dolby and DTS) and PC sound card. If I buy this kit, will it be able to play my MP3s from my PC and my DVD collection ? I did a lot of research but for newbies like me, it is difficult to understand the info and if there is any solutions at all. My sound card is quite old (sblive 5.1) and I think I don't have the correct output for Quad 99 cd-p but that could be modified in the near future but I heard that DVD would be a problem. Any suggestions ?
