I don't know what's causing it, all I know is that the video plays for 2 seconds before the video freezes. The audio still plays, though it pauses every few seconds which is annoying. I suspect that it's because his videos are too large because he wants everything to be DVD quality, I think one I tried to download was over 250MB, but since I only have 256MB of RAM I didn't bother to finish it. Several reviewers I've come across keep the free videos small but eventually offer a DVD that has everything in better quality, only Spoony doesn't do that. Screw Blip.tv.
Luckily, his review of Dragon Strike is still available on his youtube account so I can still watch it again.
