- Fixed playing files with PES packets longer than 2048 byte through the full
featured DVB card (thanks to Marco Kremer for reporting this one and providing
a test sample).
- Recording and Transfer Mode now handle more than 2 audio PIDs. For this the
interfaces of the following functions have been changed:
cTransferControl::cTransferControl()
cTransfer::cTransfer()
cRecorder::cRecorder()
cReceiver::cReceiver()
cRemux::cRemux()
