[mythtv-users] Best Crystal HD setup

[Jeff Siddall]

I have an Intel D945GSEJT frontend with a BCM970015 card running 
Scientific Linux 6 (essentially RHEL6) with these packages installed:

bash-4.1# yum list installed *crystalhd*
Installed Packages
crystalhd-firmware.i686 
3.5.1-1_2.el6                                              @atrpms
libcrystalhd.i686 
3.5.1-1_2.el6                                              @atrpms

Both of those look like they are builds directly from the latest 
Broadcom drivers.

I am using this myth version:

yum list installed mythtv*
Installed Packages
mythtv-common.i686 
0.24.1-277.el6                                               @atrpms
mythtv-frontend.i686 
0.24.1-277.el6                                               @atrpms
mythtv-themes.i686 
0.24.1-277.el6                                               @atrpms

with the 2.6.32-131.12.1.el6.i686 kernel.

Unfortunately things just don't work.  All I get is a bunch of stuttery 
video/audio as if it is not using the Crystal HD at all.  An example log 
from playing a 720p MPEG2 video is attached below.

I have googled for hours and really not found any concrete statements on 
what does and doesn't.  My questions is basically whether I should 
expect Crystal HD to work in MythTV 0.24 using the Broadcom drivers and 
if not what needs to be done to get it working?  Will using Jerod's 
latest git tree stuff work?  Do I need something that's coming in 0.25? 
  Does it only work for specific resolutions or codecs?  Is it just 
hopelessly broken?

If someone can help get this figured out I will update the MythTV wiki 
page with the information since as of now it is hopelessly lacking.

Thanks,

Jeff
