Have a look at the DVB API for playback. There are two playback
devices supported (more or less) by GPL drivers, namely the full
featured DVB cards based on the Technotrend design and the margi dvd
pcmcia card. There is also a driver for the em8400 chip, but it's not
publicly available. I also started to write a wrapper for the em8300
driver, but did not have the time to finish it.
