What I hate is NBC and ABC who like to shift television shows by 1 minute either way to make you miss the beginning of competing shows.
That's more a problem with TiVO than the networks.
The problem with TiVO is you can only record what you are presently watching.
With DVR you can record one program and watch another so the two never conflict.
Are you smoking something? You do realize that Tivo is a KIND of DVR, right?
You have a dual-tuner model which allows you to work around this problem. However, many people have the single tuner model for whom such issues are very relevant.
With my DVR, you can record two shows at the same time, and watch a third..and here I thought I had a dinosaur dvr.
I think my DVR is an electricity hog because it is on 24/7. The upside of that is that you can turn on the television, and go back an hour for two channels at any given time..I just haven't figured out how it decides which two channels.
Enter the term "receiver". When I bought my DVR from DISH network I bought ona cheap, like $75, one but it was just one receiver. meaning you had to watch what you recorded if you were home. The "dueal" receiver allows you to watch one channel and "tape" another. It sounds like some DVR's have multiple receivers now where you can record multiple channels and watch another.
