IMPORTANT NOTE:  We use standard DVD-R media for all regular DVD's sold.  It is your responsibility to make sure your DVD player can accomodate this media!  NOT ALL PLAYERS DO, as manufacters use various software codecs.  This can result in jumpy, video break-ups, skipping, and even just freezing up your video images!  We also reccommend that you clean your DVD players periodically, especially if it is an older machine; and remember, NEVER touch the video side of a disc!  On the up side, Blu-Ray players usually can play both DVD-R and BD media without any problems, however, it is HIGHLY RECCOMENDED that you visit the manufacturer's website periodically to update your BD Player's firmware in order to keep up with currrent media standards for BD media.  Using consumer cleaning discs are NOT reccommended for Blu-Ray players!
