There is no difference. The file handles are released every time.

If you look at the implementation of
cDvbDevice::GetVideoSystem() you will see, that the return value
vsPAL is the default. If the ioctl() fails, you get this value
regardless of what actualy is played.

This is currently impossible.

May be it could be a solution, to not only close the file
handles on pmEXTERN but reopen them in read-only mode. I don't
know if mplayer will work with that fine.

And I don't know if Klaus is going to accept patches in this
