OK have just purchased the TiVo today and have just noticed that it won't do what I expected!!!!

We have been using a SD/PVR twin tuner for years now and can record 2 channels plus watch a third.

Thinking that by buying a twin tuner again that we could do the same but from what I have now
read we can only record 2 channels and watch a 3rd recording only and NOT liveTV which is what we
do all the time.

Is this the truth?

Haven't tried it out yet as I'm still to try and setup the TiVo with my Airport Express later on when I have the time
so we still are using the SD PVR.

If it is the case can I split the antenna cable so I can run one to the back of the TV so when the TiVo is all used up
we can switch to watching the TV.

The SD PVR on the back has an 2 x signal in & 2 x signal out, one loops into the other and then the last goes to the back
of the TV.

cheers
