OK, sorry for the lack of details. The processor is a 3.2GHz P4 1GB memory.
The Video card is a Nvidia GeForce FX 5200, with the current driver from Nvidia. The sound card is a Sound Blaster Live! 5.1. OS is Fedora2, and the Alsa is what delivers with Fedora2. The pcHDTV is using the v4 driver released
by pcHDTV yesterday, tho David George mentions a v5 that I will try once they
get their site back up (just checked: first screen or two ok, but then the
hacker screen). MythTV from CVS a day or two ago (over the weekend).
Dave mentions going back to the dag- driver, I can try that.
Everything is running on one machine.

That would be an interesting test.
How does one play back a ATSC stream with Mplayer?
The Man 'page' is 50+ pages long, and when I went thru it I never saw
a flag for ATSC/NTSC/PAL.
But as I noted, the stream DOES play, it just stops after mabe 30s
due to what I assume is some other problem.

Well, there ALWAYS has been stuff scrolling up in the window behine mythfrontend. That has seemed to get a bit better recently (less stuff)
but since it starts w/o my having hit any buttons at all its hard to
control. Signal levels, from dtvsignal are 85%+. Signal levels from
MythTV show as 13%, which I assume is part of the scrolling problem, till
I, in a separate window do dtvsignal on a 'good' channel (I have no idea
what channel it is tuned to initially, NOT what I put into setup as the
default) then the signal comes up to the 90% range and I see a picture,
but still cant get any keyboard action.

Yes, and Yes. I deleted the non-digital stations from the setup-database,
but they were replaced the first time I ran mythfilldatabase. Guess I have
to go over to Zap2it and define a list of ONLY DTV stations

Will do, but right now I have to go into the office and finish up a couple
of projects.
Will do that when I get back later this afternoon.
