[mythtv-users] About ready to give up on g200

[Brad Corrion]

I, too, am in your boat, but I am not ready to throw mine out yet.

I was able to get artifact free video using stock XFree86 mga driver with
a framebuffer driver "in tandem" (much like the TV-Out howto describes).

Using xawtv --hwscan, I would see the two XV devices, the second being the
mga's offering.  The second xv device gave me artifact-free xawtv display.

As for mythtv, if I run iv4l1 first, I can get decent hardware compression
and software decompression.  I say decent because I am really not
satisfied yet.  there are no error-related artifacts, just blockiness in
general.  I am using a P4 celeron 1.8 with a G200-TV AGP, 8 MB.  I'm still
using PC133 memory, haven't upgraded to DDR 2700 stuff yet.  That may be a
difference.

My current problem is that with my MythRV setup working, my mythvideo
bombs because mplayer chokes.  I'm using the mga_vid/framebuffer playback
as described in the mplayer docs, and I get nearly perfect playback, but
with memory corruptions, weird flashes, artifacts, etc.  I was ready to
throw in the towel when I noticed that mplayer is *perfect* after I rv4l1
the mga tuner stuff.

So, I can either use mythtv pretty well, or mythvideo really well, but not
both from the same session.  I have noticed that my scheduled MythTV
recordings play back with the same artifacts that I used to see in
mplayer, so I am curious to see which problems are related.  Perhaps this
weekend.
