Burning during high CPU usages

[Megalith]

Just finished burning a disc (4x from USB external HD), which took 5 times as long as it typically should have. I wasn't sure why until I noticed that the new bittorrent program that I was trying out felt like using 99% of my CPU.

Well, I tried playing the disc and it seemed fine. But I'm still debating whether or not I should burn it again.

Question I want to know is, can the buffer be relied upon to protect the integrity of the disc during CPU spikes?

I never realized that filesharing software used so much ram or cpu cycles,
I wouldn't burn and download, problem with I/O disk also.

probably a buggy file sharing program

some of the new java installs are quite hefty and robust

you read my mind!

i find java apps to be sluggish in general, similar to .NET apps. ugh.

Well, I just found out about Nero CD-DVD, and I checked this disc and a couple of others that I burned recently...pretty much all of them have significant dips. But I've played them all and I haven't encountered any issues.

I've got a couple of questions:

1. I checked the discs for actual errors, but the disc tested 100% green. Thus, are these dips really even worth worrying about? What kind of errors do these dips actually imply? Does it mean that the actual data that was written may be bad, or that data was just written in a way that is less than optimal, meaning that there is a higher chance of skipping?

2. Could these dips have occurred because I was burning directly from a USB HD, which has a slow transfer rate and couldn't keep up with the burning process?

3. I deleted the .ISOs, so I can't reburn the discs. Since none of the data on the disc is actually corrupt, would it make sense to make an .ISO out of the disc, and reburn it? Or is it futile, because the dips are a permanent part of the data now?

are those dips in a transfer test?

[Megalith]

Yes, they are in the transfer rate test.

Not good, those are the bad dips, if you use cdspeed to make a data disk
then you have them as the drive ramps up speed, a benchmark transfer test
should be very smooth?
What's your burner?
The dips are just errors in the burn but the data may still be recoverable.
Try using shrink to put one of the worst ones back on the hard drive in file mode and check playing from hard drive.
