Thread Starter 
Hi all.
Title basically asked it all.
What does the cache do in a DVD burner? And does it matter that much?

It's to help prevent buffer under runs during burning I believe. On IDE when you might have 2 drives using the same connection and sharing bandwidth it was important. I don't think it matters much now.

Quick question, does the brand of DVD burners matter these days?
Between Samsung, Asus, LG and Liteon, which would you guys pick?

Personally, I prefer Liteon drives with lightscribe(useless feature but nice to have for an extra dollar). I think most drives are re-brands of only two or three companies, I forget which though.

samsung and hp drives tend to be quieter (iv had a few lg/light on that were noisy, they spin the disc at full speed even while idle for a few minutes)

2mb is the most cache iv seen on a dvd burner, less wont make much of a difference

buffer underrun was very common on many cd burners (not cd/dvd burners)
all newer dvd burners have buffer underrun protection, if the buffer runs out they will continue burning where it left off when the data catches up again
