I run Adaptec 4 on a PC running a Phillips 8x burner. I have had 0 problems loading CD-R's I have copied.
As for CD's I use, Frys sells Great Quality 12X CD-R's for 29 cents a disc with the jewel case. I can honestly say I have had 0 problems with them. They work in my Kids Sony boombox, my Sony discman, and my friends American DJ CD player.
