maybe using git, where you can pull into your own repository for privat
vdr hacking and let other people check it out may be worth a thought.

i always wondered why dvb support was directly compiled in while other
back and frontends were supposed to be plugins. this clearly leaves a
sign that dvb is the "preferd" plattform.

for me the biggest obstacle so far in many years of vdr usage. i have
already layed down CAT5 into the living room, why do i still have to
connect directly to the satelite dish to get flawless live viewing?

not only that, but also are many standard containers reimplemented in
the core source that increase LOC count for no good, at least i can't
see it.

yes, there is currently no better software for watching, recording and
replaying TV if one uses vdr with a FF card.
