Query: Problematical at best

I had a myriad of problems with this unit, including things as basic as setting the clock(easy? try and find it without the manual). It would not accept DVD Rw disks if they had ever been "touched" by another recorder(even if blank). It would not always replay the very recorded disks that it itself had made. It would occasionally miss a recording date and have the next day scheduled, as if today(for some odd reason) just didn't warrant a recording. Most of all, it had a strange logic to its controls and internal commands, neither logical nor similar to the rest of the industry, which has pretty much standardized procedures.
