To all,
We can already use VDR on our multiproto cards (thanks to Reinhard and
others).
But, for everyone who likes to use MythTV I have good news!
With the following patch you can watch TV using the multiproto API. I am
currently zapping around with my TT3200 and it works great. :)
I must admin that this patch is not what I call a real patch, it is more
a quick hack and it currently only supports DVB-S. I intend to support
DVB-S2 soon with a clean (configurable) approach within MythTV. Further,
the Channel Scanner (in mythtv-setup) once in the 3 times crashes on me
so you have to be persistent if you want to automatically scan the
channels. I am unsure if this is driver or a Myth problem.
For everybody who cannot wait, please use the supplied patch on one of
the latest SVN builds (revision 15220). I am very interested to have
your feedback/results.
Best regards,
Mario Smit
