In the Xbox Version of Xbox Media Centre DVR-MS playback worked perfectly in the builds compiled around May 2007, however after that I’m guessing the mplayer.dll was updated as when fast forwarding or skipping through a video it just skipped to the end of the video. Luckily this can easily be fixed by replacing the mplayer.dll in XBMC/system/players/mplayer/ with the one included in this post. That’s it, the fix is as simple as that, I can confirm this works perfect on the XBMC for XBOX 8.10 codenamed Atlantis build (T3CH XBMC 2008-11-13 8.10 PROPER) If you want to help try get this fixed in future builds reply to my topic on the XBMC Forums and to this bug report here, hopefully one of the developers will take note Download the working mplayer.dll
