What everybody is seeing here is very common with CD-R's. Without getting too technical on this, it's a combination of the burner, the media, and the player. Players that are certified to play CD-R's are able to accept variations in the burning process and compensate for them. When you try to play a disk on a player that was intended for comercial CD's only it's a hit and a miss. Basically what is happening is that there is a small amount of variation from the CD spec (which is different than the CDR spec) that creeps onto the media in the CDR burning process. Additionally, the CDR media is not CD spec compliant, so a little more variation gets added. As long as the sums of the variations are within the CD spec, it will play on a CD player, otherwise you're SOL.
What's even more interesting is that CD players are manufactured around some average CD spec plus a tolerance. That average can shift as long as it is within the spec tolerance. As a result, you may be able to play a CDR on one 2000 Solara, but not on another.
My advice for upgrades: Make sure the new player is CD-R compliant.
