Video Playback / Recording Devices

I have a DVD (produced in the US, I'm told it's non-regional), playing on a UK DVD payer connected to a widecreen TV, and it recognises the disk, plays the film but the image fills the height of the TV screen and so I'm missing an area at both the left and right of the picture. I think I've tried every setting on the DVD player and TV, but can't get it to show the full picture. PLaying on a computer works fine. Can anyone hep me figure out what I'm doing wrong?

I have this problem. My friend was filming my birthday with a Sony handycam. Everything was ok. But when I tried to watch the videos in the morning cam only showed question marks and after few unsuccessful attempts it only showed that movie recording is disabled and dvd is full. It even doesn't let me finalize it and when I connect it to the computer, it shows no files, but all the dvd is full. Could you recommend me a software which could fix this problem? Or at least capture my videos? I would be very grateful for your answers.
