One of my friends just dropped a Dish DP942 HDTV DVR on me. I don't have Dish and have no intention of having Dish. I was thinking about trying to set it up to record off our cable signal. Has anyone done this? It's junk to her and if worse comes to worse I'll pull the hard drive and put it in an enclosure. It just seems like such a waste to trash all that other tech for a hard drive. I'm handy with a sodering Iron and willing to experiment. Any tips or tricks? Anyone done this before? If anyone has any info on the producer/chipset/other electrical data I would appreciate it.
