1. It would be 90 hours total. There is just one unit that actually has the hard drive, and the clients talk to that unit.
2. Probably, but someone who actually owns a unit would need to confirm this.
3. There wouldnt be any reason you couldnt record in both HD & SD at the same time.
Early adopters should expect a fair amount of buginess given the history of previous Pace units on both Shaw & Cogeco.
