Thank you all, for the feedback. I have looked into this further, and
this is what I have found.
There is nothing on the web anywhere that I could find that has a
modeline that will work. It does not appear to be a mode problem
anyway. When I read up on video cards and media converters that have
composite TV-Out, the TV-Out will work with resolutions up to 1024x768.
This implies that the image is down-converted to the appropriate
resolution to work with NTSC prior to being output to the composite
video connector. Add that to the information from the MythTV web site,
and you need a new driver. Ergo, it would appear that the proper mode
is not the issue.
The ATI proprietary driver recommended on ATI's site is for Xorg Xserver
7.0. The testing release is at 7.1 (soon to be 7.2). So, unless you
can back-rev your Xorg Xserver to 7.0, forget about the ATI driver.
This leaves me with two choices - buy a new Pundit (the P2-P5945G looks
nice, uses a new Intel graphics chipset, and includes a S/PDIF optical
7.1 audio output), or buy a video card. I have opted for the video
card, because the new Pundit may only be $250 CAD, but it means I have
to purchase another new CPU. Hmm. Maybe a Core 2 Quad would work
nicely...
BTW, I had the case off, so I installed the P4HT processor I got off
eBay about 5 months ago, and presto whamo, SMP machine. (Some of you
might be saying "so what?", but I was surprised, and its the only
pleasant surprise I've had with this thing, so I'm celebrating.)
The video card is not due to arrive until Monday, however, so once I
have it up, running, and working, I will post yet another update.
Until then, soyu-snacku!
