<br></blockquote><div> </div></div>Ok, I think I've found the commit causing the issue. The reason why I say "I think" is because about half way through I had a trial where playback was a total mess but seemed to be different than before. I did two bisects at that point, one good and one bad but the ending to the "good" bisect made no sense. It stated the first bad commit was f307a3d5e60b0054e1833127d417c6acfada3213. This has to do with improving low bit rate playback on DVB-S radio.<br><br></div><div class="gmail_extra">Here is the bisect result of considering the playback mentioned above "bad":<br><br> git bisect good<br>c978683605d52fe28bb03a2ed5d112ddd7c22f8f is the first bad commit<br>commit c978683605d52fe28bb03a2ed5d112ddd7c22f8f<br>Author: Lawrence Rust <<a href="mailto:lvr@softsystem.co.uk">lvr@softsystem.co.uk</a>><br>Date: Fri Jun 14 19:53:14 2013 +0100<br><br> Player: Enable AVSync to recover quicker after a seek or program change<br> <br> The a/v timecodes can get out of step by 10's of seconds after a seek<br> or a livetv program change.
