This is probably not news to the Gurus but it fascinated me that this RAM disc( God they cost about 6 bucks a piece do they not?) took half the time to burn than a regular DVD-R- the original HDD recording was 55 minutes. DVDR took 49 minutes on Hi speed dub - A DVD RAM disc took 27 minutes. I wonder if the quality is any better? Later, I will confirm or not for us newbies. Oh my God I just had a Eureka that maybe the Hi speed mode on the Panny E-80 was only originally designed for the DVD-RAM disc and NO other type disc!!!- Of course Einstein was my Great Grandfather. I wouldn't have it any other way.
