A lot of folks have been looking for a tool similar to DVDate for HDV files.
If you have $40 to spare, DVMP Pro has finally come to your rescue :-)
From their page:
Plays files captured from a HDV and DV camcorder and displays the date and time stamp that was stored in the hidden metadata area of the file when the recording was originally shot. It also displays the timecode, user bits, and exposure settings such as iris/aperture, shutter speed, gain, image stabilizer and white balance - all displayed with frame accuracy as you play or frame-step through your HDV or DV file.
