My Sharp DVD Player/Recorder will now only play burned copies and refuses to recognise original (commercial) movie DVD's. This means a newly purchased DVD will not play on my (stand alone) player, but when processed via ANYDVD/Clone DVD, the copy will play. The originals will play on other DVD Players and on my PC. All DVD originals in my collection have previously played before; this problem has only just occurred. Logic seems to point to the player having self-adjusted to reading (& playing) only those encryption processed. Can this happen or there another solution?
