@Clint: Well, maybe you have something going there, it may have actually burnt at something like 4x, can't exactly remember how much time it used to take 'cause I've done maybe 5 or 6 compilations from my Cd collections, but maybe 40-45 minutes per burn. Or maybe 20. Dang I have no clue, I never ever tried to figure that bit out.
However my older burner (an HP 8250i? Don't remember, but it was a 4/4/24 burner) would take about 16 minutes to burn a full 650 MB CD, and those CDs also have issues with my car player. The only ones it is able to play correctly are the new low speed burns on the new writer.
When I say, play correctly, I mean: Play without extensive skipping, seek quickly to selected track, and resume playing from the last stopped point in 10/12 seconds max.
In terms of Media, I've been through three brands: HP, Samsung and Frontech. The last two are recent, HP is rarely available and is the best for audio among all three, specially if written at a low enough speed. My home player has no issues with CDs written at 24x, the max speed of the writer. Only in the car (which is subject to a lot of vibration) I have these problems. I'm working my way through a 100-CD spindle of Frontech CDs (which, IMO are brilliant and it doesn't matter since all these are made in the same factory in India by Moser-Baer) which should be over in a while, and some preserved HP blanks.
Mitsubishi is hard to find, their Blue Azo stuff is supposed to be great for Audio. Memorex is TDK, right?? The others are bargain-basement stuff I wouldn't touch.
Sorry. I Live in India. Some things may not be the same as other countries.
