I mainly use the most generic of media purchased for $15 per 100 from Compusa. I've never had any of the problems I occassionally read about in these forums. I admit to not listening to many CD's in my music room often, preferring that medium in my truck. I did a test after reading this thread by retreiving my oldest (3 or 4 year) CD's and playing them in my system, comparing them to the originals. I have none of your complaints. Beyond storage and handling changes, I can offer no 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.
