I need a new computer

So I borrowed a digital tuner card off me little brother today. Well it works, however it seems that my computer is too slow to cope with the input (it's a PIII 866!). This box actually picks up all the digital channels and seems to have no problem with them. So I don't know what was wrong with the box I borrowed off Campbell. But it also means that my aerial should work fine. This one even works with my old set of rabbit-ears, although not the aerial that comes with the box.

So.

I need two things:

  • ability to record television straight to hard drive so that I can one day retire my vcr machines
  • ability to digitise my old vhs tapes
    Actually I need three things. The third:
  • decent enough video editing software to process the stuff I digitise and burn the lot to dvd

    The first option is a hi-fi dvd recorder. If I get one with a hard drive I can use it as a vcr. The disadvantages, aside from the fact they're mostly only analogue at the moment, is that their editing is terribly primitive. Basically you can't with any control. It'd be ok for a short-medium term solution but I'd probably want to reedit everything at some point in the future and redo it all.

    The other option is a tuner card of some sort. Having established that at least one digital tuner card works here I can probably safely get a digital one. The disadvantage is that I'd need a new computer.

    So, a new computer with a tuner card and a big hard drive, and some good video editing software. What to get. I actually for a moment considered getting one of these (Dave'd be proud), but I don't think they have video inputs (I wonder if you can get a usb or firewire box with rca and aerial inputs?). Anyone have any recommendations or advice on what to get?
