[mythtv-users] Problems playing file from HD PVR

[Sarah Katherine Hayes]

The others are right though, you're pretty close to the limit for HD 
using MPEG2.  OTOH didn't someone post about a PCI card based h264 
accelerator yesterday?  If that could work in Linux (with Myth support 
naturally) it might buy you some time as it were.

As I said in another thread, I'm still trying to find a sweet spot of 
what is a realistic minimum for h264 based HD, all I've got so far is:

VIA c3-1Ghz   - NO! LOL (yeah, but I just had to try it).
Transmetta thingie @ 1Ghz - NO!  (see above)
AMD Athlon64 3400 (64bit) - NO!
Pentium 4-M 2.0Ghz  (last generation before Core) - NO!  (surprised by 
this, really thought it could do it).
Core 2 Duo 2.0Ghz (2Mb Cache) - Yes. 20% - 50% CPU.
Core 2 Duo 2.0Ghz (4Mb Cache) - Yes.

That final unit is running Windows and showed 12% CPU use, with an Intel 
IGP.  Which just goes to show what a leg up GFX drivers can be.  In all 
honesty once we get some nice, decent, GFX drivers from the ATi and 
Intel opening of the spec's that happened earlier this year... well, it 
should enable a lot more systems to play HD content in Linux.
