Hi. i have a small video production company specialising in local history and aviation videos and have recently started offering our titles on DVD. I have two problems that i hope someone can answer. If i ship a pal dvd to someone in the states will it play on their equipment. we are presently copying DVD's using an Mtech copying machine on -r format however we are getting about a 20% return rate [picture freezing etc] is this down to poor quality discs,also we have found that +r discs seem to read better in older dvd players and that the cheaper dvd players seem more tolerant of our copies,has any one else found this.
