[mythtv] Can QT be found for free?

[Alex Davidson]

I am in the early stages of determining whether I want to build a MythTV PVR
(it sounds and looks perfect and having personally used Dish Network's PVR I
am eager to get one again) but looking at the hardware and software
requirements, the only problem I see is that QT seems to be not only not
freeware, but rather expensive
(http://www.trolltech.com/purchase/qtpricing.html).  Am I wrong?  If not,
which version would I need to get and install:
1. Professional - $1,550
2. Enterprise - $2,330
3. A different version?

I'm hoping there's an opensource version or something like that.
