This seems to be a common problem but I haven't managed to find a solution that works for me. Playback is too fast and talking sounds like chipmunks. It occurs when watching live tv causing an added problem of stuttering as it appears to outrun the recording buffer and I get "prebuffering pause" errors in the mythfrontend log. It also happens with recordings but without stuttering. The recording itself is okay as I can play it very nicely using Xine (with "-V xxmc" option for hardware decoding).
I am using via xvmc as my motherboard is a Via EPIA SP13000 with the unichrome hardware decoder. I have played with various playback settings such as "Enable real time priority threads", "Use video as timebase", "Extra audio buffering", "Use hardware XvMC MPEG decoding", "Use HW XVMC VLD Decoding (Via Only)" I have set my recording size to 720x576 (PAL) and played with bitrates. I am at a bit of a loss as to what to try next. Has anyone else had this problem and if so what did you do to fix it? I'm open to any and all suggestions even ones that appear obvious or that I might have already tried (I might have overlooked something). It would be interesting to see how widespread this problem really is and if there is a common cause or solution (or set of causes and solutions) My system setup: EPIA SP13000 mobo PVR150 tuner card Mythtv 0.18.1 unichrome-20050815 (from http://myth.ivor.org/unichrome/) Thanks in advance.
