I also would like to remind the framerate issues. Naturally you decide what is enough precision and quality for you. Computer hardware usually cannot provide 50.000Hz, 59.940Hz or 23.976Hz outputs to your TV/Monitor. This will cause some judder on display output as MPEG/AVC input-stream is not synchronized to output framerate. For example dedicated blu-ray player Philips BDP3000 had a 24.000Hz output (before firmware fix) which resulted a jumped frame every 42 seconds as real input stream is 23.976Hz. It was annoying after you noticed it. But luckily now it is fixed to real 23.976 output. With this bridge we come to VGA-hardware which might have 50.01Hz closest to 50Hz signal. So every 100 frames we get a jump in picture synch. Ever seen jumping camera panning while watching a film and got annoyed by it? For ATI cards there is a dynamic framerate fix, unfortunately there is not one for Nvidia cards. Nvidia has good HW acceleration but potentially bad output. With ATI vice versa. This ATI fix fixes 50.01 by dynamically reprogramming VGA timers so real output is 50.000Hz. (General description, the author can describe more if needed). So if you aim to HD with full HD quality I'd be carefull with computer outputs. My answer was to setup Popcorn hour to output 50.000Hz with TV-stuff. Unfortunately you lose some easy-of-use with VDR as you need to have separate layer to set up etc. Also as original question came from Finland and if you use commercial HD channels they are (or at least should be) paired to your receiver. Happy hunting for HW & SW..
