Not that I know of. I can't see blocks with WMP on desktop, and I don't see them either on the device using Betaplayer of PocketTV (of course both look the same since they use 2700G decoder!).

I downloaded the most recent Xvid codec's yesterday. The blocks I see in the smallest Xvid file are just normal quantization blocks, they don't look like a bug.

I know this scene is dark, but I wanted to use it as a demo clip, so i "normalized" the gamma, so that you can see something, not just a very dark image. i agree, it will not change the quality of the blocks...

And thanks again for providing the XViD versions, it provides a useful comparison.
