I'm going to use a DVX100 to convert a signal from a BetaSP deck, so I can pass it to my G5 as DV (via Firewire). I plan to connect the BetaSP deck to the DVX100 via s-video and then connect the DVX100 to my G5 using Firewire. Does anyone know if I can pass the audio from the BetaSP deck to the DVX100 using XLR cables or am I limited to RCA for sending audio in this fashion?
