I've dug out a very old system from the loft to use in another room (althon 3000xp & nvidia fx 5500 on a km 400 pro MB )

Its running ubuntu 10.10 with the last supported drivers from nvidia (173.14.31).& a nightly build compiled today (01/11/11).

Playing a video with dolby 5.1 or ac3 or aac is a rock solid 25fps as it should be. Playing a video with mpeg2 audio is anywhere between 30 & 45fps!

Have tried all vertical blank options in xbmc & the graphics driver panel aswell. compiled xbmc without vdpau because the fx 5500 doesn't support it.

Music mp3's etc.. play fine (no speed up)

Audio options in xbmc are set to: analog,2.0,boost downmix & device is Defaults(alsa).

Output in ubuntu is set to: analog stereo output
audio HW:AC 97 Audio

any help would be great....

The problem is that the videos are in a samplerate that your soundcard doesn't support, try setting the audio device to "plug:default" in xbmc.

Just tried plug:default in xbmc & it's added a few fps! (peaked now at 48fps)

looking at the debug log i get.

can post debug if needed

Update: adding.
<audio>
<resample>48000</resample>
</audio>

doesn't work either

pressing "O" still tells me the sample rate is 48000khz

Please turn on debug logging in XBMC and post a full debug log.

It looks like you have the deinterlacer on, which doubles the fps, try turning it off or use a deinterlace method that doesn't double fps.

Thanks bobo1on1, spot on the money!!!! I Hate uk tv standards why cant we have progressive instead!

Thanks again, 25fps all sorted
