I have been using XBMC for 3 years or so to playback mythtv recordings from an HDPVR on an E350 - going from mythbox and mythtv 0.23 to PVR addon and 0.26 - previously using the fglrx driver
At the time the only recordings that played well were 720/60p (I remember interlaced didnt work at all) so I set the cable boxes to output 720/60p
These seemed to playback fine - and according the on-screen video diagnostics I seem to remember being close the 60 refresh rate
Ive just updated to the OSS driver as described here and noted comments about 36 fps limit - even though the qvdpautest indicates an H264 decoding rate above 60 - and the diagnostics show Im getting around 40-50 - but obviously many frames are being skipped which I think I can detect visually compared to fglrx (although less CPU is being used)
Just wondering what the issue is with the fps limit and what would be needed to up the speed to 60 or if its ever going to be at all possible to run at 60 with oss driver
Thanks for any information
