While it appears that Nero is the preferred burning software for many of the people in this forum, I have been using Roxio Creator Classic (Version 22.214.171.124) because it was included when I bought my NEC 2500 from newegg.
I've been burning Memorix 4x DVD-R disks recently (ProdiscS03) and although I specify 4X when I burn, the actual burn speeds that I get during the burn process are 2X (and sometimes it goes down to 1X). I've noticed during burning that the buffer seems to be depleted... it starts at 100% and then quickly goes down to 50% then down to 1 or 2%. It sometimes goes back up, and when it does the burning speed increases, but then it will go down again, and when it does the burning speed seems to follow.
I have a resonably fast hard drive: a Western Digital 7200 rmp 250 GB "Caviar" with 8MB buffer and good access times, etc. So it doesn't make sense to me that the hard drive wouldn't be able to keep up with the burning process.
Is there some other intermediate step that isn't keeping up with the burning process that may be the reason for the slow burns (usually about 38 minutes to burn a full 4.7 Gigs).
As a side question, I do have Nero Express (version 5.5, I believe). Any guesses about whether this would yield faster burns if I installed it instead of Roxio? (I would have thought burning software wouldn't have much impact on burning speed... it always seems like a media issue -- or sometimes firmware related -- in posts that I've read).
Thanks for all your ideas and suggestions!
