Is s2-liplianin working for you (apart from the remote control support) ?

The major difference between the two repositories is that s2-liplianin uses the
S2API (API v5, which has already been released in kernel 2.6.28) and Manu's tree uses
the Multiproto API (which will not be released). So s2-liplianin is much closer to
v4l-dvb and could easily be merged in. I saw that Igor synchronized with v4l-dvb
just 2 days ago. So s2-liplianin is the main mantis repository. Manu's tree hasn't
been touched for 3 months.

Why will it delay it?

Great! Please post your remote control patch to the mailing list. It would be
best to patch s2-liplianin if possible but Manu's tree is probably no different for

Me too, I would like to see s2-liplianin merged into v4l-dvb as soon as possible.

Release early, release often.
