[Solved] 3.2.0 Audio/video sync

[b0ris]

The topic says it all. Almost everytime I try to see mp4 and mkv-files I get this problem. The playback works fine from start, but after some minutes the videos goes into fast forward with the audio in normal speed, total unsynchronization.

What can I do to fix this?

Almost everytime for HBO videos? If yes, try to tick "Keep AC-3 tracks".
If audio is switched from 2.0 to 5.1 after some seconds, picture/video fast-forwarding or slowdown is possible side effect when audio is reencoded.
If not, post debug in trace level.

Keep AC-3 tracks is ticked on my computer as default and I have not touched it?

I will try to disable "Keep AC-3 tracks" and see if it helps...

It doesn't matter if on/off on "Keep AC-3 tracks", I get the same outcome as described. Any ideas before I throw my PS3 out of the window?

i see audio out of sync with the picture mostly with MKV's and its not the renderer's fault but how the MKV was built.. can you verify the videos are playable in sync in VLC player on a PC?

None of the MP4's i've made with DVDFAB are ever out of sync on my ps3...

The HBO videos works fine on VLC on my computer. With both mkv och mp4-files the video starts to go in high speed after some minutes of playback. If I cancel the playback and jump directly to where it was crazy, now everything works fine here(!), for some minutes, the problem comes back...

As I said:

If not, post debug in trace level.

I think I've come closer to locating the problem. Since I changed Audio settings 2 -> 6 channels I haven't had any problems! I was able to see movies today for the first time in more than one week!
