Query: Warning: outdated

Careful! The DVD720 is an outdated model. It has less functionality than the model that succeeded it (the DVD520), yet is more expensive. The essential difference is that one can not record directly to DVD disc on the 720 (or 725), only to the hard disc, and it is not possible to record to the hard disc from a DVD disc. The latter makes it impossible to make a copies of the DVD discs you have made by going via the hard disc. The 520 model has both functions, but I found it so noisy on playback of R & RW discs (and crash prone) that I returned the one I bought.
