Trouble with Nero 6 and 108 with DVDs

I got a DVR-A08 to replace my Plextor 708. First thing I did was burn a 8x DVD, everything went fine.

After about a week I got in my new 16x DVDs and started to get buffer under runs, slowed down Nero real bad. Started to move the speed down, now I have under runs even at 4x. In one week I went from 8x fine now 4x bad, the dvd burns fine, but takes forever now…

I have no idea what has happend, other than a update to nero…

What can I check and try to get to the bottom of this??

DMA mode is ok, files are on a SATA raid tested by nero at 79,000 kb per second…

Will scan for virus tonight, takes forever with KAV…

Any help would be welcome, I have burned too many dvds just to get the speed up…

Found my problem. It was the cable, now everything works fine…

Just a quick comment for other folks out there too - it’s always best to tell Nero to cache files smaller than around 128K or so. Even if you have a fast drive and a fast burner, sometimes the act of making the hard drive seek from here to there for hundreds of small files (if you are backing up data that is) can cause underruns as well - it’s sometimes better to burn to an image first for this reason.
