Burning a CD


I recently made copies of several hard to find CD's (Lyrita Label) loaned by a friend using my home computer CD burner. I have noticed over a several month period that the recordings seem to be degrading; I am getting a jittering sound. I am using what I think are decent CD's (Imation), and wondered if this is a common problem and what it's cause might be. I am pretty sure it is not my CD player as all commercially made recordings are playing flawlessly. In general I prefer to buy either new or used CD's so I have the liner notes etc, but sometimes that's not an option and I really would like to be able to do this without problems arising later when I no longer have access to that hard to find recordings. Any ideas of where to start.

Gboren is 100% right on about the audio optimized blanks.

When you burn an audio CD on your computer don't burn at super high speeds. I don't recommend burning higher than 4x. Doing so will sometimes results in too many errors and will cause erratic behavior in audio CD players - it will also result in the drop-outs that some folks have mentioned. If you burn at 4x on good quality media you will end up with discs that sound great and last a long time.
I burn at 1x for masters. 2x for personal use. Nothing faster. I have used many blanks including the imation, which has been inconsistent and thus I use them for family video editing. The ones that have been pretty consistent are the memorex. As I recall there was a thread a while back that went into the different manufacturers and where there actual discs were made. I think there are not that many actual places that make blank CDs, but rather there are dozens of companies that market these blanks. The result is that you want to get blanks made from the "good" source. Some "manufacturers" (meaning imation et al) get their blanks from multiple sources--thus they are inconsistent. While some work with only one source. I do not know these sources, nor do I know which manufacturers use multiple sources, but hopefully someone that does will join this thread.
Imation has been lots of problems for me. I use the audio TDKs now without any problems whatsoever - and at 8x speed. Arthur
Believe it or not, the CDR's that I've had the most trouble with are the more expensive ones such as TDK and Maxell.
To obtain better results, on my computers in the past I slowed down the read speed to 1x and the recording speed to 1x. But with my new computer, I seem to have no control over the read speed and not much control over the burning speed. Does anyone know how to gain control of those two settings? [XP Home OS]
