Just about to build a new system. Since drives are bottlenecks I'd like the fastest available. I will want separate DVD reading and DVD burning drives for maximum rates.

Samsung SH-223 is just about the fastest DVD-burner you will find at 22x. Not too shabby read-speeds either.

I need to duplicate HQ DVD's in bulk, and I'm looking for
a inexpensive of cheap way of duplication. I've used Kukani
before, but yo have to wait to receive them in the mail and
honestly I wasn't impressed with the quality.

Anyone know of a good way to reproduce HQ DVD's
from my PC on the cheap?

Yeah I've tried Kunaki; takes to long. The best thing to do
is just replicate them yourself. I make digital products &
"How to" videos. Now that Ebay has banned the sale of
digital products, I think a lot of people are going to need
a cheap DVD duplication system set up, or a reliable
outsourcer.

I'm a little impatient so I just burn them myself. There's
this guy who sales a course on how to duplicate DVD's
& CD's without comprimising quality or creative options.
Check it out if you want. One thing to remember though:
if you get the right set-up, you can bust DVD's out basically
at cost, which will save you a grip over time.

I need to know a dvd burning software to download for free. They are AVI files off Utorrent. I just got a new laptop so I don't know the exact software it comes with other than I know it has a cd/dvd burner.
I have windows vista. Nero doesn't work with vista
What if I want to watch it on a dvd player? Rather than my computer

Here is a step by step guide to burn DVD from any video formats. It works well for me.
