I did a search on AO for MythTV and couldn't really find what I was looking for. If there is a thread with this info on it let me know.

I have a few questions about MythTV.
I have to be honest I heard about it for the first time yesterday.

1. What are the pros and cons of MythTV over TiVo?
2. Is it really more expensive than TiVo or is that just starting from scratch?
3. How hard is it to setup/maintain?
4. What are the capabilities of it?
5. Is it worth the time investment verses the perks?

Any other cool info about MythTV would be appreciated.
