If you are talking about V4L, we have a period of two months without
maintainer. During that period, we lost compatibility with 2.4. Also,
some contributions were not tested with older versions. We did an effort
to test backwards compat until 2.6.8.
DVB is another history. They don't provide backward compatibility. In
fact, their CVS is meant to compile on the latest -mm or -rc kernel
version. We had to remove some DVB code from V4L three because of code
conflicts caused by this. Also, DVB code on V4L is backward compatible
with 2.6.12 and 2.6.13. With the merging scripts, we also provide
compatibility with DVB development tree. We may provide backward compat
with other DVB versions providing that somebody interested on it provide
us patches for it.

You may do it, if you wish. But it would be nice to keep duplicated
codes "read-only" on ivtv. If you guys find a bug or want to send an
improvement, please send to V4L mailing list for us to apply. Then, you
may copy the newer version. This way, we will avoid having duplicated
code, with different patchsets on it.
