[mythtv-users] To TiVo or mythTV it

[Rich]

Not new to Linux but very new to PVR.  I have some questions that I can
not seem to find answers to, short side of buying and trying.

1. Is there a straight to the point running document that compares the
functionality and ability differences between TiVo and mythTV?

2. Now for a loaded question.  For those that have gone the mythTV route. 
If you walked into COSTCO and saw a Series2 TiVo 80hr box sitting there
for $268 with a $100 rebate would you have rather bought that or dumped
$1200 into a Linux mythTV box?  Would your wife agree?

3. HD-2000 vs. HD-3000.  I realize many may not have the 3000 yet but this
might be best answered by those that have used the 2000.  Why buy the 3000
when the 2000 has two coaxal reception ports?

4. On the surface it looks like there are more PVR vs. pcHDTV cards in
use.  Any opinions as to why?

Thanks for any input given and your time taken to do so,
Rich
