Sony RDR-HX900 DVD Recorder with 160 GB Hard Disk Recorder
Sony RDR-HX900 DVD Recorder Very Good But Could Be Better
I have used this recorder to record to DVD+R, DVD-R, DVD+RW and DVD-RW.  It performs as advertised.  I have used it to record movies from premium cable channels.  The fast dub feature works great.  I've used it to record from old VHS tapes.  There are some limitations to each type of recording.  Chapter marks that are made to a recording on the hard drive are not transferred to the disk when dubbed.  More editing and titling features are needed.  I have not used the TV guide feature but it seems to work fine as long as the unit is left turned off for a period of time each week so that it can acquire the information.  Users of this machine should expect to spend considerable with the instruction manual to learn its features and limitations.  From what I've seen this is probably one of the best DVD recorders with a hard disk on the market.  I would expect to see improvements in the next generation of this type of equipment.
