The DVB broadcast is dumped straight to disk - video and audio so you
don't need an audio card to record the sound. But you do need one to
play it back. Are you saying you don't have a sound card?? If that's
the case then you won't be able to play back the audio from that
machine because the video part of the recdording is sent via the
TV-Out of your video card, and the audio part is sent via your sound
card to your speakers/amplifier/whatever. If you don't have a sound
card then won't be able to hear any sound.

I can send you Sydney's if that's any help. If you need it please let
me know which tables you want me to send you and I'll export them.
