Not arguing for the sake of arguing here, but aren't HDV cameras only recording audio in MPEG-2 (or maybe AC3, i.e. lossy) format? Even though it's 16/48, it's still an MPEG audio source you're left with, correct? It might still sound good, but it is technically lossy if it's MPEG-2 or AC3 audio.
Whereas a DV cam can record in 16/48 LPCM (lossless) format.
And NO, I'm NOT saying any HDV camera is a bad choice or anything of the sort. I've seen some beautiful, beautiful footage shot with HDV cameras. I'm just pointing out technical facts inherent with various camera formats.
