for reporting a problem with ensuring there is a current audio track in case there
is only one track
for enabling a device to detach all receivers for a given PID
for modifying switching to Dolby Digital audio in live mode, if the driver
and firmware can handle live DD without the need of a Transfer Mode

for providing 'libdtv' and adapting the EIT mechanisms to it

repeating timer (thanks to Marco Schlüßler).
- No longer removing superfluous hyphens in EPG data - would become too
language dependent to handle all kinds of exceptions.
- Modified switching to Dolby Digital audio in live mode, if the driver
and firmware can handle live DD without the need of a Transfer Mode (thanks
to Werner Fink). Live DD mode requires a full featured DVB card and a
LinuxDVB driver with firmware version 0x2622 or higher. Older versions will
use Transfer Mode just like before.
