How Should You Clean A Dvd

 I recently rented Sleeping With The Enemy at my local Blockbuster,and I played it on my computer,and the movie stopped right in the middle where it was playing. So the next day,I took it back to the store,and got credit for a free rental. As for what I consider weird is that DVDs can be cleaned,unlike a tape-it's just that idea kind of seems strange compared to CDs and CD ROM discs:I know DVDs hold much more information than a CD,but I wouldn't wash it with liquid soap or window cleaner:I'd probably use glasses cleaning liquid and a cloth.
