Panasonic DMR-E30S Progressive Scan DVD Recorder
Panasonic Loses DVD Format War
I bought the E30 and am very disappointed.  A technology like this is so promising.  The DVD RAM disc cannot be played on any other player except this machine or a machine that can read DVD RAM.  Most DVD players do not have this capability. DVD-R cannot be recorded again once the disk is finalized which limits its usage as a substitute for a VCR.  I will be be returning it and purchasing a Philips which supports DVD+R and +RW which delivers on the magic of DVD recording.
