hm guess you're right. done that.

ok got that.

i know it belongs to the ivtv mailing list but you seem to have (a
little) insight there: do you have any infos when such a stable release
will happen,
and won't it be 0.2 since in the readme states 0.1 isn't developed
actively anymore. (i think that interferes with ck's efforts doesnt it?)

seems reasonable to me.

stable api is always good, means less work if the api doesnt change.

hm it seems as if the vbi support in the newer ivtv drivers is already implemented.
i posted a msg on the ivtv list on this topic and awaiting answers.
so if it would be (re) implemented to work with 0.1.9 and mythtv it
would probably only live until ivtv > 0.1.9 is released, (because it
will then be supported by the driver) the mythtv - changes may persist
if they work with the new drivers or will need to be reimplemented. that
sounds like doing work twice doesn't it?

thanks for the hint. i'll try to bear this in mind for my future
postings (guess this one's ok?!)
