Couple things.
PVR has 2 tuners and can do the following:
Watch recorded show and record 2 shows
Watch live TV, record 1 show
If you press the off button on the PVR while its recording, it will not shut off. The problem is if the PVR is on while recording and you turn it off it will not shut off after the recording. However if you set a recording and the PVR is off it will turn itself on and record and then turn itself off.
I cant asnwer your question about the remote as I have a harmony remote - I would highly suggest getting one if you have more than a few devices.
I have the following hooked up Samsung Tantus 4234 TV, Denon Audio, Phillips DVD, Shaw PVR, XBOX 360, PS3 and I can control all but the PS3 (there are a few funtions that work but not all) with one remote. Its a bit pricey at retail stores here but you can get if off Ebay for about 300$ Canadian including shipping.

Harmony does eat batteries but if you go that route you will never regret it - I would suggest the following Energizer Fast Charge Batteries - they work well for me, they are a smidge noisy when recharging but I have used the same 8 AA and AAA for my home devices and they dont seem to have ost their charge after about 16 months of constant use.
