That sucks! There's no way to swap boxes and save programming? How about connecting the two boxes in some way? Maybe through a usb cable or something? Any Ideas?
Connect a VCR or DVD recorder to the composite (or s-video if your recorder can do it) and the l/r stereo outputs of the dvr and play on the dvr and record on the vcr/dvd ... that's the only way to get content off the box ... unless you have a device to records from firewire. that port is active too.
