People who today have difficuty with MythTV recordings' HD playback
1. using inadequate frontend hardware
2. using a non-Nvidia video card
3. using an Nvidia video card but not the Nvidia proprietary drivers
4. trying to play back HD-PVR recordings without a VDPAU-capable video
card or a Core 2 Duo 3.0GHz
2 is very rare, nowadays. 3 happens sometimes, but is easy to remedy
unless in an unusual situation like a Mac mini. 4 is also rare because
anyone savvy enough to run trunk for HD-PVR support presumably knows
about the heightened playback requirements. That leaves 1.

It's--no exaggeration--not possible to buy a new desktop computer
that doesn't have enough CPU horsepower for HD playback. It hasn't
been possible for going on two years.
 Except, again, for an unusual situation like certain mini
ITX-based systems. Or so I gather; having never seriously considered
buying one I don't know for sure.

What's wrong with that?
The three most-powerful computers in my house are, in order,
* Storage server/slave backend (December 2006).
* MacBook (July 2006; also can run mythfrontend).
* Frontend/backend (November 2005).
None was top-of-the-line at purchase, although the storage server's
capacity was admittedly extreme then and more or less still is
today. The only one I might replace in the next 12 months is the
MacBook, and it won't be for MythTV-related reasons. I bought my
frontend more than three years ago at a Fry's Thanksgiving sale. VDPAU
means my frontend might run for another three years.
Frontend/backend: P4 3.0GHz, 1.5TB software RAID 5 array
Backend: Quad-core Xeon 1.6GHz, 6.6TB sw RAID 6
Video inputs: Four high-definition over FireWire/OTA
Accessories: 47" 1080p LCD, 5.1 digital, and MX-600
