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.

You can pick up DVD-RAM's at WallyWorld in a 3pk for $12.97 (~$4.30 ea)

Thats just because DVD-RAMS burn at 2x speed compared to 1x speed for DVD-R. However DVD-Rs are available in 2x and even 4x speed, but the Panasonic DVDR recorders apparently only support DVD-R burning in 1x mode, if they upgraded their drive you could burn as fast (or even faster) on DVD-Rs as DVD-RAMs!

Thanks for the replies guys- Those new Pannys coming out sound very good. Question is ... will the E-100 be able to burn in 25% of the time the E-80 can on a 1x or 2x disc. Is it the disc or the machine?

The reasons why DVD-RAM is faster have been posted, but are you sure that you're dubbing DVD-R in high speed correctly? Or maybe your HD source was recorded in XP? The amount of time you posted is potentially quite different than my experience. I just got my E80 last Thursday but have burned about six DVD-Rs since then, all off the HD from 2:03 VHS tapes that I fed in at SP, and the time to burn to disk is about 56 minutes - less than half the time of the original recording. I think your high speed dub only cut off six minutes? The only way I can think that that would happen is if high speed wasn't really going or you were using XP and consequently had twice the data.

cf- I ONLY use xp(because I want best res and will use 3 or 4 discs) to record FB games or classic movies(but that is all I record anyway to archive.)- hi speed dub only reduces it by about 6 minutes unless you use ram(which cuts it in half) or some weird 4 x disc. Most people only have 1x or 2x dvd-r's blanks.

Chris,


High speed dubs to DVD-R are pure data transfers conducted at 1x which means that regardless of the original length of the recording and the recording mode, a transfer of a full disk's worth of data will always take about 56 min. Hence, both a 1 hour XP recording and a 2 hour SP recording will take about 56 minutes to transfer. For non-high-speed-dubs, the dub takes place in real time (i.e., less than 1x speed) and is not a pure, lossless data transfer (re-encoding occurs) even if the dub is done at the same quality mode setting as the original.

Houston,


I don't think the DVD-R media rating has anything to do with the time it takes to do a data transfer. The burner in the E80 can only do 1x burns to DVD-R regardless of the speed rating of the media. The E100 has a 4x capable DVD-R burner and can therefore do faster high speed dubs than the E80. See above for explanation of a 1x transfer vs. real time dub of an XP program. Bottom line is that all E80 high speed dubs take a maximum of 56 minutes regardless of the real time length of the recording. What determines transfer time is the percentage of disc space used, so a 1 hour recording in SP mode would take half the time of 1 hour recording in XP mode to high speed transfer.
