For real. A lot of people I've worked with assume an HDV tape will play in anything a DV tape would. On one occasion I had a colleague call me up for a favor assuming that since the HVX shoots HD the tapes would playback and he could capture his footage and I had to disabuse him of the notion. To be honest I would prefer some form of compressed HD shooting to HDV to the SD deck, that way you can hand off your tape you're shooting an event for somebody or something like that but you can still say you're shooting "HD." I can only assume that incorporating the software or hardware into a P2 would be prohibitive in some way. But then if I refer back to that story, HDV tapes are a pain in the ass to capture unless you have an HDV deck, and oh there's different versions and maybe this needs to be captured off of the camera they were shot on even. So for that kind of convenience DV tape does make more sense.
