I have a blue ray player and sometimes the DVD i'm playing will freeze up and skip up to about 30 min of film. If i rewind it I can see what i miss and sometimes it will play forward again without freezing but most of the time it will freeze up in the same place all the time. This freezing in the same place all the time would lead you to believe it is dirt or a scratch on the DVD but this has happened at least a half dozen times to brand new DVD's right out of the wrapper! if its the player then why freeze up in same place all the time only to certain DVD's?
