VCRs

2-3 years at the most.

Box top DVD recorders are already available, just costly. If the price on them comes down as fast as DVD recorders for computers did though then they'll be commonplace soon.

Some peope are also buying digital recording devices as they are in an affordable bracket. If you have Bell Express Vu you can get the 5800 reciever for $549 Canadian which has digital recording built in, not too sure what the recording length was off hand, but it was a lot. =)
