I've recently used radio mikes with a camera mounted receiver (channels 1&2) in combination with a boom plugged into the XLR jacks of the adaptor. Worked very well.(posted 9056 days ago)For extreme long lens shots, and situations where radios picked up too much interference, I've had success with the Sony Mini-Disc.
Of course, this ignores timecode concerns. I simply synched on my Non- Linear editor and output my final from that.
I'd like to add that sound is almost more important that picture quality on DV films, and is often slighted. If you can afford going DAT with a great sound crew, do it. If you're going really low budget with student crews.... well, I've seen films killed by unskilled sound people using DAT with boom and mixer. It's a tough job to do well. To my way of thinking, radios into the camera + boom into the XLR adaptor, is the most forgiving and gives the best result (but be sure to rehearse for sound only so your operator can check the levels).
