[mythtv-users] Gentoo + VIA Binary driver

[Mikhail D'Vane]

Hmm... I'm running Gentoo on my M10K and playback at 480x480 resolution is
smooth (CPU at ~50%).  I needed to apply the EDX hack to cputest.c, though,
since I have a stepping 3 CPU.

A few questions:

1.  What kernel are you running?  I'm on 2.4.24-epia1.  (I've also had 
success
     with 2.4.25-epia1, but I didn't notice any difference in performance).

2.  What's your CPU stepping?  (Look in /proc/cpuinfo.)

3.  Are you sure that the EDX patch has been applied?  Depending how you
     chose to install MythTV, it's possible that cputest.c got overwritten.  
To
     install on mine I have to use a slightly different approach than normal
     emerge.  I have to:

    - ebuild /usr/portage/media-tv/mythtv/<mythtv-ebuild-filename>.ebuild 
unpack

    - go to the unpacked work directory and edit cputest.c

    - ebuild /usr/portage/media-tv/mythtv/<mythtv-ebuild-filename>.ebuild 
merge

4.  When you refer to binary drivers, do you mean the binary video drivers 
or the
     mpeg decoder driver (libddmpeg.so)?  I don't currently use the HW 
decoder
     (can't apply any filters with it), but I have used it in the past and I 
found
     you can pretty much just replace the libddmpeg.so file in the library 
with
     whatever version you wish (Via's, Ivor's).  Performance/issues are 
different
     between the various versions.
