X handles the output that MythTV generates, at least in most situations. 
(Using a PVR-350's TV output would be one exception.) Thus, X must consume 
some CPU time to process this output. Normally X won't peg the CPU use at 
100%, though. I don't know offhand what specifically might cause this, but I 
have seen variation in X's CPU load when playing different types of data.

I doubt if I'll be able to provide more specific help; however, you'll greatly 
increase your chances of somebody being able to help if you can provide some 
additional information:

1) What video card (or other output method) are you using?

2) What driver and driver version are you using for your video card?

3) What's your output device? (Computer monitor, NTSC TV, PAL TV, digital
   TV [and if so, what format]?)

4) What are your video settings? (Resolution, bit depth, refresh rate,

5) What version of MythTV are you running?

6) What's the title of the DVD that's giving you problems, and for what
   region was it marketed?
