I purchased this GO Video unit specifically to play DVD recorded in the DVD+R and DVD+RW formats. The Amazon.com technical information states that this item is capable of playing these formats. However, the owners manual that comes with the machine only lists the DVD-R/RW formats and even then states that some of those may not play.As it turns out, I was unable to confirm even these capabilities as the DVD player would not even play any of several commercial DVDs without locking up with a frozen display that no button on the remote or on the face of the unit could affect. Only turning off the power and restarting would allow some control to be restored.I have returned the unit as unsuitable for my needs.
