Thanks for you reply. I was hoping to get some information of the type
Mplayer did note that there was AC3 sound in most of these streams,
though I didn't bother to cable things up to see that it had actual 5.1
content. (The Sempron machine that I'm playing with this on doesn't
have enough power to play things in MythTV; I scp'ed the *.mp2 to my
Xeon workstation and played them there.)
You're right that the 4:3 content inside the 1080i frame looked way
better than normal NTSC. I attributed that, though, to getting pure
mpeg2 instead of digital cable -> cable box -> composite NTSC -> PVR250
-> mythtv. It would seem that they could just send 480i or 480p
digitially and get the same result, but maybe changing formats all the
time isn't a good idea.
I'll try azap over the weekend and later firewire as I move toward
implementing things. I don't yet have an HDTV, but hope to do that
soon. I'm not going to drop the $1000s for it until I'm satisfied that
I can control content. (I'd rather watch NTSC when I want then HDTV as
a slave to the networks. Two years of MythTV and hundreds of Gigabytes
of cheap disk space have spoiled me.)
