Interesting - so I tried an experiment with my two mac minis.  Both
contain 2.0 GHz Core 2 Duo CPU, 2GB RAM.  However, one uses the older
(and much maligned) Intel GMA 950 GPU, and the other (my Myth
frontend/HTPC) uses the newer Nvidia GeForce 9400M.  The GMA 950 plays
back 720p flawlessly, but the Nvidia GPU mini spews the "dropping
frame" messages every few milliseconds when playing 720p recordings
from ABC and FOX.  Pretty ridiculous, as I bought the Nvidia model
specifically for performance as a HTPC...
At any rate, I updated the ticket.
