The ivtv module is not required for the pvrusb2 driver to work.

The presence of absence of the ivtv driver should not at all affect the 
pvrusb2 driver.

I can't vouch for the ivtv utilities; I don't use them here.  But I 
imagine that any such utilities which stay within the standard V4L APIs 
(including the recently added mpeg API) have a fair chance of being 
usable with the pvrusb2 driver.

Yeah, building out-of-tree drivers can be a pain.  A similar headache 
appears when building the standalone pvrusb2 driver (as opposed to using 
the version in the kernel) - best I can do there is try to make it as 
painless as possible.

The ivtv driver however is about to appear in the kernel tree.  In fact 
I think it may have been accepted into 2.6.21 so fairly soon it's going 
to get a lot easier to use ivtv.
