I'm currently downloading the build you have specified, so I'll give that a go later.

As I am no developer, I doubt I would be of any use, but I am keen to resolve this issue and any logs/traces/tests you would like me to perform, so if there is any way I can help, please let me know.

This may seem a silly question to experienced users, but would there be anything to stop me trying your 0.25pre build? (http://downloads.sourceforge.net/project/mythtvformacosx/Development/MythFrontend-0.25-intel-10.7v0.25pre-20120310.dmg) Or can you not mix backend/frontend versions? I'm just curious to see if a more current version of MythTV resolves the issue - I must admit I have had this issue for some time now, and have been *hoping* that with every update that problem would go away :-(.


@ James Linder

Thank you too for your input into the discussion.

Reading the list recently, I was of this opinion too. However I think (unless I have mis understood you) that you may have misunderstood my issue: It is my NVIDIA Mac mini which is having the problem, where my ATI iMac plays everything back silky smooth - this does't really add up to me.

Is this a known bug then? Or just with ATI GPUs?

Thank you too for your input into the issue I'm having

The idea had crossed my mind last night, that it would be interesting to see if a distro such as Ubuntu from a LiveCD would playback the same recordings ok on the Mac mini. However, I would prefer to keep MacOS X on the Mac mini as, apart from this issue, I have a fully setup media centre on the Mac mini and I don't really want to have re-set all of it up again, just to 'work around' this issue.

For now, I'll see if I can get Linux running from somewhere on the Mac mini, and try to see if I get the same issue under that environment.


Thank you all for your time.

Kind regards,

Joe
