So the sample I viewed Is DVD quality? And so the DVD Is higher res. The download version should be better quality, because It looked blurry to me. The sample looked crisp. This Is what I have:

GISample 1024x768 res Audio:Bit Rate 32kbps

GI Modeling Part.1 800x600 res Audio:Bit Rate 24kbps

So the sample Is higher in res and audio. But before I buy any dvd I want to know for sure Its better quality, because I may never get the downloded version of the tutorials again If the dvd Is higher quality.
