macro blocks using DVD2ONE ?

I think your answer lies in your question. If the same data plays differently on different media, then it is a media problem. It may only be that your player has difficulty with a particular brand, though, and not truly defective media. btw - macroblocks are a coding unit, not a visual artifact or defect. I understood your question, but I'm one of those people who gets hung up on details.

Thanks mpucoder, you're right, I'm speaking of the square blocks, that appears when the DVD player can't read it properly (sorry for the confusing ...) The strange thing is that 1 DVD_R (Princo) plays perfectly, and another (same brand, same pack) doesn't play fine. I didn't mention that the squares don't appear in the same scenes each time (if I replay the chapter, it works fine, and the problem overcomes further). I think that my standalone player supports Princo media, but that this brand may be inconsistent in quality (I noticed some dust inside my second pack - I cleaned the DVDs but that might signify that manufacturing is not so reliable) . Do you think that's the point ? I'm gonna try the same process with higher quality media ... Too bad if that's it, blank DVDs are still expensive in France (~5$ each, vs ~1.80$ for the Princo ones ):mad:

off topic but... 

I think this is a media problem, and so I'm moving the thread to the forum dedicated to these problems.

princo=crap not from experience but from what i've heard.

Thanks to everyone I think now it's really a media problem (nothing to see with DVD2ONE !!!). I had heard that Princo was crap, too, but I don't always trust what "one says ....", I wanted to try by myself, and the first pack was pretty good. I was less lucky with the second one, but the third that I'm burning seems good, too. So Princo = crap -> I don't agree. Not absolutely reliable, OK. But twice cheaper than others in France, so it worths some cloasters ... I bought some Memorex in Luxembourg (where I'm working ...) at 3.30 euros (prices are decreasing, now). Gonna try, and I'll let you know if Princo is the real guilty !! Bye. Fuerte
