    If you are using an Nvidia card, then the remedies for Catalyst driver problems will not fix it.

    So, my question is, has anyone get 1080p content to play on the x1250?

    Using CoreAVC as h.264 codec the 1080p plays smooth (AMD X2 BE2400 with 2x2,3 GHz). The only issue is playing 1080i. The x1250 does not support ANY HW-acceleration to h264, the CPU has to do everything. Deinterlacing of 1080 signal is way too much for a CPU.

    With any other codec than CoreAVC (ffdshow, Cyberlink etc) i does not get smooth playback for 1080p.

    Unfortunately, thats the rub with HD content. There are alot of scan lines and pixels there and something has to have the horsepower to process it (whether it be a CPU or GPU). If you dont want to upgrade your CPU, then the only option you have is to slap in a video card with full x264 acceleration. Don't get me wrong, you can probably tweak codecs and get better performance, but there is no substitute for running low cpu utilization.

    Yes, I've got it! HD h.264 1080i/p, 720i/p playing smoothly with acceptable deinterlacing with the x1250! I can even watch live DVB-S2 HDTV! with my X2 BE-2400 CPU (2x2,3 GHz)

    The clue was the new CoreAVC 1.6.5! With MP you have to use deinterlacing option "blend". With MediaPlayerClassic even deinterlacing option "hardware" gieves excellent result. Option "wave" is withou deinterlacing, not good, option "bob" is way too much for the CPU. Deinterlacing option "hardware" does not work with MP (with VMR9 I get no picture only sound, with EVR picture but freezes).

    I don´t buy a cheap video card with full h264 support because my barebone does not have any 16x PCIe slot!

    CPU usage:
    (Athlon X2 BE-2400)
    1080i: 74-95% (live TV from DVB-S2)
    1080p: 27-51% (Narnia trailer)
    720p: 14-27% (Narnia trailer)

    I cant believe this!

    Tried latest Cat. (8.1). Now here is what I found so far:
    - No fix for FlipY (as expected)
    - No "Force 1080p50 (PAL) (sadly expected)
    - 720p 50 (PAL) REMOVED!
    - Mini-view does not work properly

    Thank you very much for making it clear that I should get a nVidia next time, Ati :)

    Don´t be upset. 60 Hz is much better to the eyes than 50. Get FlipY repaired with installing Vista. Vista works miles better for my x1250/690G board (all annoyances sorted out like: flipy, 1080i HDTV, black level, mpg2 DXGA, better standby etc)

    Well, 50Hz is must if you are watching PAL material or you will end up in the jerky playback when 25fps is tried to sync to 60Hz (wich is not possible).

    You are right, sync is not possible. But the graphic card can make a pulldown like correction, I assume? NTSC users watch 24 fps movies corrected like that (3:2 Telecine pulldown) every day. It can´t be sooo bad or jerky. I activated "pulldown detection" Avivo CCC (dunno if it is important, but recommended)

    Pal dvd does not play jerky neither does 1080i/50. It does not disturb me. I tested sveral times forcing 50 Hz and e.g. scrolling text was not fluider (set it back to 60 because overscan correction is otherwise nit possible).
