[mythtv-users] split-second freezing on HD channels

This mini-ITX system contains:
* Processor = 1.6 GHz Atom 330 Dual Core Processor, 64-bit, 2 Cores, 4 Threads
* Memory = 2GB DDR2 800 (PC2-6400)
* Video = Intel 82945G/GZ Integrated Graphics Controller, i915 Kernel driver

It runs a myth backend and frontend.
It is connected to a single tuner HDHomeRun.  That's all.

In Utilities/Setup -> Setup -> TV Settings -> Playback ->
Playback Profiles (3/8) the Current Video Playback Profile is
"High Quality"

This gives the best results.
Tried the other profiles like CPU, Normal, Slim, etc.
Nothing works as well as "High Quality"

Yet, when watching some Live TV HD channels:
1. Every couple of seconds, it suddenly freezes and then continues.
2. Each freeze is only for a split-second and its gone.
2. Then it will stop doing the freezes on its own.
3. It only happens HD channels.
4. During regular programming and commercials.
5. Sometimes this freezing does not happen at all.

Any suggestions?
