    This is not really a bug - but I suspect it to be one - needs to be confirmed.
    -Widescreen monitor is using it's native resolution.
    -the screen calibration is done, and the square is completely .. square.

    now: Satellite channels looks OK.
    but the analog TV, "Hauppauge WinPVR USB2 (hardware compression)" is "never" looking perfectly normal, no matter what aspect ratio is selected.

    Could somebody comment on this ?
    .Maybe it's a Norwegian phenomenon, as Norwegian terrestrial TV often messes up cropping/aspect ratios, at least over shorter time, like commercials and news.

    I suspect there's something fishy about the analog TV.
    - it worked "perfectly" in version 2.3.0 - and no TV server.

    Please tell me what you think about this .. - remember - SAT and movies/episodes (AVI) are *always* ok.

    I have the same Problem with my Creatix CTX946 Hybrid DVB-T Cards with Hardware Encoder for analog. DVB-T Video is fine but the analog tv has the problems you discribed. You can try a different codec for mpeg2 in my TV. But there may be other problems like missing deinterlacing or sometimes timeshift errors ( powerdvd 8 ). Right now i just searching for the best codec!

    Having a similar problem, aspect ratios watching TV in 2.3.0 was fine, but since upgrading to RC1 yesterday aspect ration needs manually choosing for each channel, and none of them seem perfect (or if they do not reaching the edges of the screen), I'm having a look through to see if any codecs etc were deleted when I switched.

    Same problem here. My TV is widescreen, but it seems like MP treats it as 4:3 when playing TV, since 4:3 shows fill the whole screen, while widescreen shows stubbornly have black bars above and below the picture. The net effect is that everything is stretched horizontally.

    I tried both with the MPV and ffdshow codecs, and even fiddled with the AR settings in ffdshow, as described in another thread, yet nothing seems to make any difference. I also went through the screen calibration, and the square used to correct the AR is indeed perfectly square (I even measured it with a tape-measure).

    How does MP determine the aspect ratio of the screen it is being used on? The resolution of my screen is 1280x768, which works out to something closer to 16:10 than 16:9. Could that be part of the problem? I believe 1280x768 is a pretty common resolution for widescreen panels though.

    System info: Windows XP w/ SP2, MP RC1 (ReVision skin), Hauppauge PVR-250 + PVR-500 with latest drivers, Asus M2NVP-VM mobo with latest NVIDIA drivers.

    Any help is appreciated.

    jup fixed that problem for me too. Another option is chance codec from MPV to PowerDVD or something else!
