Ok, lets see if i got it right: My Nvidia 6800LE has dvd-decoding capabilities, and my NF7-S v2.0 has dolby digital, But to use these features i have to buy Nvidia dvd decoder?
i thought all 6800's had broken video bits and thus the purevideo wont work on them!? i downoaded the trial version of thingy and it kinda sucks the audio quality is fubared and video looks no different than it did before ,so no i dont think you need the software well not with your 6800 anyway
