plugged into the PDX10's 1/8" (3.5mm) stereo audio input, it *should* work. I downloaded the PDX10's manual from retrevo.com and the PDX10's XLR adapter instructions are on page 29. The instructions say the XLR adapter's cable attaches to the PDX10's accessory shoe. There is nothing in the instruction manual referring to that accessory shoe being the Sony Advanced Interface Shoe ("AIS") So... I am going to say that it will not work with any of the current HVR series camcorders.
You might find the XLR adapters from juicedLink or BeachTek more useful as they will work with the HVR series camcorders and any camcorder from any manufacturer with a 1/8" (3.5mm) stereo audio input jack. Use care when deciding which model XLR adapter you get - your mics may need phantom power and not all XLR adapters provide it.
