It would compile today's snapshot of v4l-dvb with an old kernel version
(for example 2.6.16)? (or is better to upgrade the kernel?)
Trying to compile today's mercurial snapshot in a SuSE 10.1 (2.6.16-21),
give the next errors:
/root/v4l-dvb/v4l/bttv-i2c.c: In function 'init_bttv_i2c':
/root/v4l-dvb/v4l/bttv-i2c.c:411: error: storage size of 'info' isn't known

Not long time ago v4l-dvb community had discussions about dropping
support for kernels older than 2.6.22. And community decided to
support kernels 2.6.22 - 2.6.30+. One of the reason that it's big work
to support code to make it compiles and works in old kernels. Well,
developers want to spend more time working on new code.
So, the best way to you is to upgrade your kernel.
Second way to correct mistakes. Probably developers can help you here.
One more way, probably you can take old snapshot of v4l-dvb repository
that compiles and work on 2.6.16 if you need. Someone can point to
link to it (i don' know).

Well, this mistakes appear in v4l-dvb daily build too.

The issue should be fixed with the current tip. I just added a backport patch
that will restore backward compilation starting from 2.6.16
Cheers,
Mauro
