Robert, you are absolutely right but I took this information from the Sony HVR-S270 manual, where it's called
4CH/FS32K recording. It makes no mention of HDV/DV. Further, I have a JVC BR-HD50 HDV deck sat here on my desk and I double-checked that - 2ch HDV/up to 4Ch DV. HDV
tape did not have 4 channels, that is true. But the OP mentions
HDV with 4 channels. Therefore I think these clips must be actually
DV. Unless the Sony camera has a way of non-standardly combining the DV sound format with HDV picture. In any case and according to that camera's manual, they will be 32KHz, since the total bandwidth of DV/HDV tape could not accommodate 4 tracks at pcm (or mpeg) 16bit 48KHz. The information you found does not refer to any camera format but appears to be MPeg-2 for DVD and such.
I did edit my post but I should have been more careful in checking. Back in the day (and I still have it) I shot a lot of material for both corporate and broadcast on DV and HDV, with the JVC HD101E. It does not have 4 inputs but before that I had a Canon XL1s with an optional XLR back that did have 4 inputs for DV. My broadcast Sony DSR-570 DVCams did not have 4CH inputs though as I can remember.
