Sorry for the vendor link. Here's one.
There must be others and I think Walmart has two models near me.
Looks like all the DVRs on the market require a subscription to TiVo. I've got no beef with TiVo, but why can't you find a DVR that records analog cable like a VRC, except to a hard drive?
I'd like the option of recording without constantly swapping tapes or recording multiple simultaneous events. Seems like the hardware should be able to do that without a subscription service as the middle man.
