One of the movies he ran was the latest Spiderman which had the bars. When I saw it at BB, it was running full screen, and looked perfect.
Funny you should mention it. I was at BB yesterday and saw the same thing. I asked the guy what the source was, and he said it was bluray. So I grabbed the remote and fiddled with the picture size button, and sure enough they had set it to zoom to fill the screen, which of course removed a lot of content. I shook my head and walked away. I was actually there to get a Y cable for my subs, only to be told that it shouldn't be done and that I should spend $80 for a monster (there I go swearing again) sub cable that came with one included. I promptly left the store.
I watch a lot of stuff via my HTPC, and never have a problem with losing content. The black bars are pretty standard, like these guys mention, check the disk for the ratio and you'll know what to expect.
