Just wanted to chime in and say I've noticed the same thing.  0.24 on my identical Mac Mini played back everything flawlessly.  I have an HD-PVR and an HDHomeRun single.

0.25 playback stutters from time to time - though I wouldn't say it makes mine unwatchable.  I do notice that it gets worse over time and restarting mythfrontend alleviates it for a bit.  I honestly have been too busy lately to even think about looking into it, or I'd have filed a bug report with a log by now.  I currently use VDA Normal, though I have tried all the VDA profiles with no luck.
