I got rid of my Mpeg-IV player for a HTPC, the DVD player did play most but not all. Ogg/OGM, subtitles under AVI's, jerking, audio/video out of sync, and HD incompatibility. It was annoying connecting up and transferring the files that wouldn't play onto the laptop, then setting it up, enable S-Video out, set TV out as primary, connecting optical USB dongle, using keyboard/mouse WMP etc. So take 30 minutes compared to 10 seconds on the new HTPC.
