Dandy,
Although it was not the case with your equipment failure, this seems like a good place to remind video shoppers that SD cards also fail (and possibly, more often than the most reliable versions of the PV-500). So, to avoid losing too many shops on a long day of video, many of us will never put more than 2 video shops on a single SD card. I seldom have the time on a video route to stop and review video between shops, so it's really important for me to stick to this routine.
BTW, you were fortunate that you were, apparently, doing v-shops where you could return and reshop to save the fee. In 10+ years of video I have never had one that was not a "one-and-done." That, and the large fees for such shops (and travel bonus on many) really increses the stakes for a failed shop. I'm curious what industry you were shopping, as there is so little video done in retail, dining, etc. on the Mid-Atlantic region where I find most of my shops. Always nice to hear from another v-shopper.
