Jeff,
You've hit the nail on the head. In following the suggestions of the
other guys, I updated my burner firmware, the Roxio suite to 8.05, and
uninstalled the secondary IDE channel. I didn't try the registry changes
to force DMA because I'm not using XP.
(For the record, before uninstalling the IDE channel, the settings for
both devices on both channels were as follows: Device type: Auto
Detection (grayed); Transfer Mode: DMA if available; Current Transfer
Mode: Ultra DMA (grayed). After rebooting, the secondary channel
returned with the Transfer Mode defaulted to PIO only; I set it to DMA
if available.)
I started burning with all the above changes. Still the snail's pace. As
I looked closer at the progress display, I saw that what's taking so
long is an encoding process. So far, it has taken 20 minutes to encode
7% of the first 20-minute movie. None of the lights on the burner are on
during this phase, so the actual burning probably will occur at high
speed once the encoding finally ends.
While this was going on, I returned to this NG and read Jeff's post.
It's clear that's he has identified the real problem.
Now the question becomes, how to speed the conversion to VOB? Are there
specialty programs that could do it faster than what's included with the
Roxio program?
While it's moot at this point, in response to def456 I am using Maxell
4.7GB DVD-R 8X blanks. Dave, the wonderful links you thoughtfully
provided are mainly geared to XP, so as noted above I didn't try
registry changes.
Thanks to all.
Ray
