I have seen several variations on this question and suspect it may be more
than one possible problem.
I recently upgraded from MythDora 3.2 to 4.0 with a reinstall. I did not
have this problem in 3.2.
While watching a baseball game, mostly all was OK, but while watching a
large thing in motion, like a man running, the white uniform would
"stretch" along the axis of motion blurring out like a cartoon character
leaving streaks behind him. The blur looked pixilated and "caught up" when
the guy stopped.
Were you watching the game "live" or as a recording?
What resolution were you doing the video capture at?
What resolution were you doing the playback at?
I have read several descriptions of things that may be the same thing.
Some were MythDora specific, some were not. The recommended fixes include:
- taking off interlacing (but where and how?)
Controlled from the Utilities/Setup -> Setup -> TV Settings -> Playback
- uninstalling video4linux (I only have the video4linux-devel package and
it claims dependencies, so I'm leaving it for now)
This should only be a problem if there is interference with one of the
other drivers. Since most other stuff seems to be working I would leave
it alone.
- doing some mojo with the nVidia card (nVidia Corporation NV18 [GeForce4
MX 4000 AGP 8x] according to hwconf)
Which video driver are you using? The open source driver is the nv,
while the NVIDIA proprietary driver is nvidia. You need to look in your
/etc/X11/xorg.conf file to find out, or look in the /var/log/Xorg.0.log
file to see which one got used.
Which playback choice did you make? You should choose the Xv and not
XvMC. The Xv playback works with either driver even though it takes some
more CPU power, but you have plenty to spare. But it also has fewer
artifacts. The proprietary nvidia driver works better than the open
source nv driver, but you might try the nv driver first to make sure
everything works first.
I know my way around Linux but am a real newbie on video stuff.
Does it help to know I have 2 PVR-150s and the CPU is a AMD Athlon(tm) XP
2000+ 1.66666?
TIA,
PS: The Padres won 7 - 1. I credit their speed on the base paths, which
was enough to cause streaking.
Are you positive the problem is with MythTV at all? Could the white
streaking have been caused by the TV station making the broadcast?
