Hmm, yes this is a very, very old bug. It was there from the very beginning.
The idea is that when you are in radio mode, then a call to S_STD should
switch you back to video mode. So there should be some additional
administration here to keep track of the video input and set it back to
that, rather than just choosing the tuner input.
Of course, abusing S_STD for something like this is dubious as well, but it
is rather low on the long list of things we can improve.
To be honest, I don't feel terribly compelled to go in and fix it. I'm a bit
too busy lately :-)
Regards,
Hans
