[QUOTE="jerrbe, post: 346311, member: 85973"] I recently setup a HTPC in my livingoom. This is a clean windows install and a clean install of MediaPortal RC4. The PC is an Athlon 64 3000 with 2GB of RAM. I have a hauppage tv tuner and both media portal client and tv server are running on this box. Whenever I playback a DVD the audio is fine but the video occasionally (every couple minutes) jumps. I searched the forums looking for potential answers and nothing I found seemed to help. I finally resorted to using windows media player to playback the DVD and I had the exact same problems. My next thought was that my DVD drive was having issues. I ripped the movie to the hard drive and played it back from disk with the exact same results. About the same time I also noticed the jumpy video when watching tv programs I had previously recorded with Mediaportal. Finally I opened task manager while playing back the DVD. My CPU burden was around 10% while the movie is playing, but each time I had a jump in the video I also had a spike in CPU burden. I started watching the specific processes that jumped in CPU usage at is was always the TVServer service and the MYSQL service. Once making that discovery I stopped the TV service and now DVD playback is smooth and CPU burden stays around 10% the whole time. Manually stopping the TV service each time I want to watch a DVD is NOT a practical solution. Does anyone have any ideas on why the TV service would be causing video playback to jump? Can you think of any settings I might change to make this problem go away, or is a dual-core CPU a requirement for smooth video playback? :D Thanks [/QUOTE]
