Hi all... I just tested all of the various discs available in Meritline's "Hi-Speed" DVD pack and thought I'd post my results. (sorry if this has been done elsewhere here)

Here's the pack: http://www.meritline.com/dvdsamplers.html

I used the same movie for each test. My system: 2.53Ghz, 512MB Ram, Creative 6x for rip, Sony DRU-500a 2.0f for burn.

BTW, this drive LOVES Verbatim and TDK 4x discs and will burn them full-speed with never a problem... besides the high price of course Here's the Meritline discs:

All 4x DVD-R media:

102-091: OptoDisc 1x-4x : 4x ok!: 14min burn - Great discs!!
102-092: BeALL 4x: 2-3x:23 min burn (going to re-test more)
102-002: Meritline (Ritek-same) 4x: 2x:30min burn
102-096: Accu 4x: 2x:30min burn
102-074: DVD Pro 4x: 2x:28min burn

Verbatim confirmed at 4x (15min burn)
CompUSA 2x works great (30min burn)
TDK 4x work great (15 min burn)

Hope the info helps someone...
