Minimyth error "Video frame buffering failed too many times" on aspect ratio switch

Description
Since upgrading to 0.22, my main MythTV frontend gives the error "Video frame buffering failed too many times" when fast-forwarding past a change in aspect ratio.
For example, "Family Guy" is broadcast on BBC Three via DVB-S as a 4:3 aspect ratio picture. The trailers before the programme are 16:9. If I try to fast-forward past the trailers, the picture freezes when it gets to the 4:3 content, then returns to the menu with the error message as above in a green box.
A mythfrontend log of this happening (at timestamp 11:09:46.132) is attached.
This happens on a frontend which is an EPIA-M6000G motherboard, attached to an LCD TV via VGA cable at 1360x768, running MiniMyth? 0.22-73b4. The same thing has happened with previous versions of MiniMyth? (0.22-72, 0.22-73b3), and also when the same frontend was running 'proper' MythTV on its own hard drive.
Other frontends, e.g. my desktop PC and my laptop running Ubuntu 9.10 and MythTV 0.22-fixes, don't see this error.
The error did not occur with 0.21.
The backend is running MythBuntu? 9.10 with MythTV 0.22-fixes.
I'll try to make a small recording that causes the error available.

I've extracted a fragment of a recording that displays the error, and put it at http://fbcs.co.uk/files/7319_20100125232800.mpg
If I view that recording on my MiniMyth? frontend and fast-forward at 20x, it gives the error described above.

Thanks for the clip. Could you please post the full output of 'mythfrontend -v playback'. I need the extra detail around the resolution change.
Thanks, Mark

Verbose mythfrontend log with error at 16:21:02.747

I've attached a verbose log as requested. Because the clip is short, it seems less reliable at reproducing the error -- I think sometimes playback hits the end of the file instead of hitting the problem. On this occasion, I had to try three times, fast-forwarding x5 or x10 as soon as playback started: on the third attempt the error message appeared. As a result, the log probably contains a lot of stuff that may not be relevant. The error in questions occurs at timestamp 16:21:02.747 in the log.
cheers

There have been a couple of fixes in this area and I can't reproduce the issue myself. Pushing back to 0.24 to see if Chris can confirm whether or not it is fixed in 0.23.

I haven't got a 0.23 system with the same hardware to try it out on, so I'll just keep using the latest 0.22-fixes and report back if it gets fixed.
cheers

Chris,
Any fix in .23 is unlikely to find its way to .22-- This ticket is probably going to stay in limbo unless you are able to test with .23.

Tom Lichti on the mailing list reports this issue exists in trunk.

I've now updated my backend box to Ubuntu 10.04 with mythtv 0.23-fixes, and the frontend to minimyth 0.23-73b9.
And I can report that the problem has gone away!
Thank you to everyone involved in 0.23 -- it's looking very good so far.
