I swear I saw this somewhere, but, can't find it.
The last few days I've (finally) been watching my PWG DVDs. Starting with Life During Wartime, up to (currently watching) Ninety Nine.
I noticed that the commentary audio tends to just completely blow, volume wise. Excalibur is almost always loud, and clear, but, the guest commentary tends to be very low, if even audible. (see Hero's commentary on the 6 man opener on 99)
I know it's not any kind of revelation, on my part. But, that kind of stuff seems like it'd be the easiest stuff to fix/correct, depending on how they record it.
Anyway, just wanted to vent it, a little, as it makes watching the DVDs at 3am hard due to the difference from the silence, to Excalibur's louder excited moments.
