First of all glad you got the DVD. There couldnt be any commentary really unless 1, I stood next to the camera and commentated or 2, ran the video through the production stream and did all the titles commentary after the fact. 3. If i did #2 it would of reduced the quality because that source is straight from the tapes themselves and it would of been down converted and processed about 3 times.
The HD master source is the highest quality I can achieve to disc at this point. Some of the other DVDS have commentary and titles but those are from either live disk recording or stream sources. Live disk recording through my production ala tvmike.tv are pretty high quality but dont get to the hd master level because of processing.
Just an explanation.
