burning tool is pretty much user's choice, i did experience some drives didnt like some software, IE my old dvd burner hated nero burnt coasters all day and roxio worked like a charm. i say go with something you use, imgburn is free and great if you dont have anything yet.

burn speed is somewhat grey, some people say burn at media's max speed for best write, and some say slow is best, personally i go with slowest or 2nd slowest speed. think its a old habbit from cdr but try burning something at 4x then 16x, oddly the 4x leaves a darker mark on the dvd for me and i call it "deeper burn" (or i'm crazy and just imaging things) oh i do burn stuff i give away to people i dislike at 8x or 16x heh

*Edit*
oh forgot to mention some also say theres a sweet spot (or speed) for some media, like burn this at 12x but another brand at 8x etc

and finally i guess to answer your question...
Imgburn
4x, 6x, or 8x
speed setting is up to you, at 3x i think there should be slowdowns in some game movies, but at 6x it will play fine
kinda for people who beleive running at 3x will make their dvd drive last 2x as long, but unconfirmed i'd say theres also a noise/vibration issue on 6x
