I guys, I live in New Zealand and we don’t' even have (and may not get for a few years yet) HDTV. So from what I understand MythTV is not really that useful to me?
What I would like to do is have a media centre PC or maybe even just an Xbox that I can play movies on, DVDs, maybe games, and music. I would also like to have the functionality to record TV programmes, sports events and movies however I won't be recording HD content, just analogue (free TV) and digital (Sky TV) signals.
I've been using mythtv in a split setup (pc backend, xbox frontend) for about 2 years now, watching/recording analog cable, DVB-T and DVB-S. Works perfectly for my needs (recording off 5 sources, in 2 different timezones, with some really weird cable lineup)
If Sky TV in NZ is encrypted like the UK one, you're in for some fun... you basically have two possibilities:
The analog way: you'll need an IR blaster to control the Sky receiver and an analog card to record the output of the receiver (quality isn't that great doing it this way).
The digital way: you buy a dreambox 500s, flash it with the neutrino image, use your sky sub card (and receiver serial number) in the dreambox and setup the dreambox as a remote recorder in mythtv.

Can you record television onto an Xbox? If not, what software would you recommend? I don't mind paying money as long as its not subscription based!
I guess possibly in the long run I would rather have a PC because it’s easier to upgrade. Can you use an external hard drive with an Xbox for instance?
Recording tv on the xbox is not something I'd even try. It may be technically possible (tv tuner through USB1), but due to the low specs of the xbox I don't really see a point in it. Same remark for the hard disk, I'm not sure USB1 would give you decent speeds for good quality content. This is why I'm using a split setup... that way I have the xbox under the tv, one network cable going downstairs to a more serious machine doing the recording and storage.
I'll concede to reality_storm that MythTv isn't exactly trivial to setup, but it gives you a very flexible solution that runs no problem on old machines (been running the backend on a celeron 667 for close to two years, before upgrading for transcoding).
Hope that helps,
