Ivor - PS - nothing new in Xorg.0.log

And - apologies for the bad wrapping. Here's the mythfrontend -v all output
again. Methinks the BadAlloc is to blame.

Ivor,

Thank you very much for responding.

1. I guess mp2decoder isn't working. Mp2player x.mpg gives:
	starting up mpeg2 video testapp...

 	found 24bit TrueColor
	beginning to parse the Xvideo extension...

	Chosen Xv port: 64
	XvMC error in file xvmc-test.c line<110>:
 		Exiting.
	Fatal error - exiting.
	Run time: 0 frames in 0.00 seconds.

2. I'm using your basic Via Epia ME6000; the fanless one. 256M RAM. I
mention RAM because at the end of all this "free" gives:
             total       used       free     shared    buffers     cached
Mem:        223444     217856       5588          0      58928      43600
-/+ buffers/cache:     115328     108116
Swap:       458744       8672     450072

But I would imagine that's what swap is for.

1. Can you try the sample mp2decoder application from the unichrome site,
that 
will test whether your decoding is working.
2. What hardware are you using.
3. Can you get a "mythfrontend -v all" log for the failing playback. 4. What
do you see in the X log when you start playback.
