Burning Tiao Yuden 8x blank media.
Have been told to burn at 4x to get a "good burn"
Is that good advice?
Does it matter?
Also could some one explain the reason why less of the DVD surface is burned in an 8x burn than in a 4x burn?
The burn surface should be the same regardless of the speed since it relates directly to the amount of material. With small projects (under 1GB) you can run into situations where some burning software will burn a minimum of 1GB and other software will only burn what you have (burning at least 1GB is usually done because some players won't play a DVD with less than 1GB of material).
IMO speed of the burn isn't as important as how well the drive burns. Some drives just burn poorly at any speed. I've read that burning at 4x or 8x is better than 1x or 2x because there is less jitter - don't know if this is true or not.
I routinely burn at 8x and have never had a DVD returned because of the burn speed - have had a few -R's come back because of booktype issues on older players, but never because of burn speed.
I've been bunring with LG's (4 set, converted recently to 7 set) and Pioneer - no complaints with either. The robot with the Pioneer gets "picky" sometimes, but as of yesterday when I brought the 7 LG's on-line the robot (Bravo 2) seems to be worried about employment and is doing better (actually, I think the robot has a heat issues as I've been working it overtime lately - 2000+ burns in the last 2 weeks). The LG's were picked based on the reviews at cdrinfo.com
