Nicer than any tvout on any vid card I've ever seen... would you agree?
Just a quick question... did you use a crystal for the 3.58MHz color
subcarrier? Is that the trimmer cap you're talking about? I had a bugger
of a time getting it calibrated, as I don't have a spectrum analyzer. I
did have an RF generator, though. I ended up setting it by tuning up
3.58xxxMHz into the RF generator, using it for scope sync, and trying to
"freeze" the output of my card.
You all are making my head explode!
Basically, I tried to use a signal generator to tell me that my
crystal was tuned correctly. They were both free-running, but I got them
to sorta lock on the 'scope screen. Like I said, the *real* solution
would be to make a 525/2 PLL off the HSYNC and use that for the
color subcarrier. For most TV's, it probably doesn't matter that much.
If you were doing more advanced stuff (broadcast-ish stuff like wipes,
chromakeying, etc), it wouldn't be good enough.
IIRC, the DisplaySize is supposed to be units, not pixels... like
inches or cm. The ratio of them will set the aspect ratio mplayer/mythtv
uses to play, but it's also used to calculate the dpi of the Xserver. Now
that I RTFM, I see it's in mm. Try different values (in the same 4x3
ratio) and see if you can get the scaling right. I seem to remember I had
to set Mythtv to use extra-large fonts.
Yeah the units is in mm. What I like to do is figure out what DPI I want
(usually 75) then calculate DisplaySize depending on the resolution I want to
run.
mm = Pixels * 25.4 / DPI
For example, if I have a 1680x1050 display, and I want 75 DPI:
1680 * 25.4 / 75 = 569mm
1050 * 25.4 / 75 = 356mm
(of course this could be simplified to just pixels * 0.339)
Just for the record, I looked through my configs. I'm still using
NVidia driver 6629 (I haven't had a need to mess with the box). Also, my
DisplaySize is set to 160x120, resulting in 114x101 dpi according to
xdpyinfo. I think my MythTV fonts are on the largest that comes default.
I still say it would be nice to have an "interlaced" theme for
mythtv. No point in having the CG stuff blink so badly, but certainly not
worth turning on a "deinterlacing" filter on the vid card.
Hope that helps.
