I had a try at running a UK disc in windows xp under the virtualbox, it seems I
still get the fuzzy imagery that I saw in Linux while it was trying to play the
same region 2 disc, now, when I pressed pause and slow play, at times, the
imagery cleared up to what it should look like, also, the sound was good, but
did have issues, I would imagine therefore the issue is somewhere with video
processing, I installed the Nvidia graphics adapter non-free as it recommends,
what else might there be to consider?
