I have an e55 on order but would like to record on it and playback on my existing panny dvd player (ram compatible). I realise after much searching that the e55 is geared up for caddied ram disks, but will uncaddied disks be a problem or not? Or what I am basically saying is, does any one here use uncaddied ram disks on this machine regularly without any problems? If so, which make and where are they available? Thanks a lot for any replies.
