mythtv svn. ("mythfrontend version 0.19.20051208-1")
athlon64 3000+
geforce 6600 gt
gentoo 2.6.15 and nvidia 8000 series drivers
pchdtv 3000 picking up unencrypted QAM.
pvr500...not doing anything at these times.
1 gb ram
250 gb sata drive.
dell 2405fpw set to run at 1920x1200 in x11, so a 1920x1080 (1080p) or
1920x540 (1080i) hd feed has native resolution

frontend and backend on the same box.

my fox affiliate is currently spitting out a lodef feed (the exact same
thing as on the analog channel)...i turned on xvmc decoding and myth's video
feed freezes up 2 seconds in when i try to watch it. (the video stops
coming, but esc quits back to the main menu)
however, after much trying i managed to tune to inhd and watch a hdtv feed,
it plays fine.

both work (but hdtv stutters) with a different mpeg software decoder chosen
in the frontend settings.

is this something i need to upgrade to the absolute newest svn to fix...a
new issue that i need to provide someone with details on so a fix can be
added...a setting i need to change...or something else?
