Nah, there is an even larger problem: DVB-S2 implies a max Srate =
30MSPS and DVB-S implies max srate = 45MSPS. There are quite a load of
nasty quirks like that with the current API. Another one is that, the
user application will never know whether a tuning failed or not. Well,
most of those application developers did want those quirks and hence we
do have them.
Interesting, isn't it ?
