    Next week I'll get a new Athlon II X2 245 to replace my current Athlon X2 4850e. This has HT3 and MAY be able to do 1080i (but probably not VA). At least it should do VA antialiasing on my 576i sources.

    Too bad if you need more powerful gfx.

    Small tip - get AMD Athlon II X2 240e version instead, it have better TDP.

    Runs fine on my system, SHIFT+! = no droped frames, 50fps, very smooth video, audio seems ok.

    I have a feeling your GPU maybe too slow, or is not mediaportal is not using dxva properly. I know you think that your GPU is fast enough because it plays fine in VLC, this comparison only suggests that the .ts file probably isn't faulty. VLC uses software decoding whereas you probably have mediaportal setup to use hardware decoding. Also mediaportal 1.0.1+ has higher hardware requirements for renderering than other video playing software.

    Try the following
    • Check renderer (XP=VMR9 / VISTA=EVR / WIN7=EVR)
    • Run graphstudio and check what codecs are in use.
    • Increase Mediaportal priority to ="Above Normal"
    • If you run the video in a small window (instead of fullscreen) is there an increase in performance/less dropped frames. Alternatively if you lower your desktop resolution (eg. 640x360) does the file play smoothly?
    • Overclock your GPU, is there an increase in performance/less dropped frames? (To overclock you need to increase both the vga core, and the memory bandwidth) - On AMD iGPU to increase the memory bandwidth you have to increase the HT frequency, which involves overclocking the FSBUS) - Warning overclocking can burn your computer if you don't know what you are doing, otherwise it's quite safe.

    Another thing you can do. Try playing the video in Mediaportal 1.0 Final, if that works smoothly then the problem is your GPU isn't powerful enough for latest mediaportal version.

    I can only get a maximum of about 10fps on two different PCs I've tried it on now, even in windowed mode. On this PC here in the office I have an Nvidia 8500, on the media PC it's Intel G35. On this PC (Nvidia) I can see that CoreAVC is using CUDA, which obviously I don't have on the other PC. I can see that MP is using about 20% of CPU, yet it still won't play this video. How come it plays fine in VLC? Graphstudio shows that I'm definitely using EVR and CoreAVC.

    Sorry to sound stupid - how do I check this, please?

    (1) Are you saying that when you play 1080i video using CoreAVC you only get 20% CPU. Try then disable CUDA in coreavc, then rewatch the clip, what CPU useage do you get, is it any smoother?

    (2) Nvidia 8500GT is too slow to hardware deinterlace 1080i and render @ 1920x1080 using latest version of mediaportal. (you need to upgrade gpu, or go back to MP 1.0 Final, or use software decoding, or avoid 1080i)

    PDVD h264 codecs or arcsfot codecs (both in HDPACK 2.3) do a better job of hardware deinterlacing than coreavc. however i think your onboard gpu is not fast enough anyway.

    If your keen to give the best shot possible -> The other thing that sometimes work, is reformat computer, fresh OS, then install minimun drivers (gfx/sound driver), just install 1x codec (PDVD H264 from HDPACK), then install mediaportal, select PDVD codec for h264 video and set renderer = EVR, now try the video. this will eliminate potential software/codec conflicts.

    AFAIK - There is no easy way of checking if dxva is working, other than checking you meet the requirements, eg direct graph from codec to renderer in graph studio, correct renderer for OS, correct codecs in useage, file in dxva compliant (which it is bc i tried it).

    This did the trick. DXVA on both MPEG2 and H.264 for 1080i sources at 60fps! Finally! :D

    Wow. I tried a GT240 with no success. Maybe I needed a faster CPU to help.

    That's exactly where I started from - definitely too underpowered to handle interlaced HD. Moved on to the ATI 3550 which worked fine for MP1.0 and below, and had to go to a 4670 for MP 1.0.2. The 3550 really didn't cut it when it came to using DXVA to do HD, and the only way I could get anything decent out of it was to use CoreAVC. The 4670 just works, pretty much no matter what codec I throw at it, DXVA on / off. Still back on 1.0.2 on my production system, so not actually using DXVA atm so I can keep subtitles.... will get to 1.1 when RC 1 comes out.

    Adding DXVA subtitles to MP 1.0.2 is really easy. Just go to the integrate MPC-HC subtitle engine thread, download the binaries for MP 1.0.2, and overwrite the files in the mediaportal directory. And then subtitles dxva glory with MP 1.0.2. Only takes 5 sec to install.

    CPU shouldn't matter much. I only have 0-20% CPU useage with DXVA (AMD4200+)
