[mythtv-users] HDTV on EPIA SP13000

Has anyone actually got this to work well?
  I've read this post to the dev list: http://mythtv.org/pipermail/mythtv-dev/2005-December/042588.html
  but I can't even get close to the results he claims.
   
  With Via XvMC selected I can actually watch HDTV without the CPU being the bottleneck, but some channels / programs it will be very close. CPU usage is usally 70% - 95% watching HD content depending on the format and program. The video is smooth enough, but the audio is choppy no matter what I do. Enabling AC3 passthrough makes it much worse... any ideas?
   
  The other thing is the video only works on 720p and SD channels, 1080 channels just show a blank screen with audio (that isn't choppy ironically). Perhaps I need to make the code adjustment from the post above? I'm hesitant since I rather rely on gentoo than do a hand compile, but you can only set the framebuffer memory to 64M max in the BIOS, so I'm suspicous there isn't enough video memory for 1080. I've set the framebuffer to 64M, I've got 512M in the box... I wonder if the bus could be the bottleneck??
   
  Would appreciate if anyone who has watchable HD on an EPIA would share what they did.
