I am going to try using 1x or 2x in the future and see if this solves the issue. The CD's started out sounding good and ended up sounding bad after as little as 6 months, but I was recording and burning at 8X. Also, my experience with the real cheepo CD's such as the $10 for 100 varieties were that they are totally un-useable. Thanks for all the helpfull suggestions.
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.
