[pvrusb2] Fuzzy Video using Hauppauge WinTV PVR USB2

[roger]

I think I've found your solution.  Seems I did document this issue on my
webpage:

http://www.eskimo.com/~roger/programming/pvrusb2.html

See my very last entry:

(2005.08.08) Noticed Mythtv requires quite a bit of cpu.  However, if
you're noticing Mythtv use >99% on a ~1Ghz pentium3 cpu, you might want
to try recompiling sys-libs/glibc (and ensuring you have included some
cflag optimizations such as "-march=pentium3 -O3 -pipe
-fomit-frame-pointer".  This seems to be the second report of compiling
glibc w/o any optimizations caused Mythtv to use more cpu then one would
expect.  Another idea, echo 1
> /sys/class/pvrusb2/sn-7435104/ctl_interlace/cur_val.  (These are some
ideas if you have already tried every other config setting within
Mythtv's menus.)


In brief, recompile sys-libs/glibc with some optimizations such as
"-march=pentium3 -O3 -pipe -fomit-frame-pointer".

(In the meantime, for the past month, I'm running into a bug where
mythtv freezes when starting to playback video and am experimenting
recompiling mythtv and glibc here.)
