    Posted in RC3 forum post by accident first. Here is the info:

    Im having the same issues with 24hz playback. I am using AC3 filter as the decoder and have tried directsound and reclock and both exhibited the lag. It seems to trail the video slightly. I have been using AC3 filter instead of ffdshow audio because it has caused a slight stutter in 1080p material. I will do further testing with ffaudio but would appreciate people still looking into this issue.

    Please post a small part of the movies your having problems with so the developers can try to find this bug. I actually deleted all 24hz material and only went for the DVDs (PAL) I already had.

    I have remuxed the only blu-ray I have to a 23Gb m2ts file. It plays fine but with the same out of sync problems in MP after I click on some error message about some decoder that can not be found (probably HD sound or something, it doesn't actually say what decoder). It play's fine in MPC.

    someone has any idea how I can make a small example to post here?

    I will try to get some sample up tonight. The sync issue is not horrible but is noticeable. I will need to figure out how to to trim a portion of video without modifying anything.

    I've this problem too... I've a big CPU usage... sometime to 100% too with all 24p video (simply divx, too) and obviously when 100% is reached a frame is dropped :eek:

    The same movie works with 30% cpu usage with Windows Mediaplayer :mad:

    My system is a Athlon X2 3600+ (only a core used... in reality :oops:) with NVIDIA 6150 integrated GPU...

    I'm using MPC as codec, fddshow for video postprocessing and for audio decoding...

    With 25 or 29.97 files all is OK... there is really something broken in 24 fps playing :mad:

    I'm using the HDMI output on a ATI HD3450 card for both audio and video.

    I've changed the refresh of my screen to 25 Hz and using Reclock to change the slow up the audio the CPU usage is slower :eek:

    It's pity that this solution is unacceptable I've bought a 24p display and now Mediaportal is broken at 24 Hz and I MUST use 25 Hz :mad:???

    I hope this will fixed soon...

    Please post some example videos (about 90 Mb or so) which show the behaviour for the developers. I myself cannot rely on my HTPC at the moment due to other problems... So I cannot verify and post the examples myself.

    Got that same problem too. audio not synced and stutter problems.
    My HTPC is connected via a HDMI-cable to my LCD-TV.
    Now I had the idea to use the VGA-input of the tv. I thought, that something could be wrong with the HDMI-signal.
    I changed the cable and it seems to work. I had only a "natural 24hz stuttering", audio was sync every time I jumped forward or backward. :)
    I tested a few movies and everything was better than before. VGA was better than HDMI. Don't know why.
    Resolution is the same => 1920x1080. But here I used 60hz!
