Hi Paul
Answering your last question first; the slave units are about £60 plus
postage of around £4. you need a slave unit for each multiplex you want to
record simultaneously, but usually one slave is all that's needed as each
unit will record multiple programmes simultaneously on the same multiplex.
So, for example, if you want to record bbc1 and bbc2 at the same time, you
only need one unit as they are both on the same multiplex. But if you want
to record bbc1 and ITV at the same time, you need a master and a slave unit
as they are broadcast on different multiplexes.
MP2 recordings made with digi TV can be played back using the software but
it can't be played back with winamp for example as the original soundtrack
is recorded on one channel and the audio description voice is put on a
different channel and the two tracks are multiplexed and merged together
when digi TV plays the file.
It is technically possible to demultiplex the sound tracks using the demux
tool under the file menu.
This leaves you with two separate sound tracks which I suppose it would be
possible to merge using a wav editor such as sound forge. But I've never
tried this and I suspect the tracks may get slightly out of sync after a
while.
But if you want to try this you can re encode MP2 files as MP3 using CDEX.
But once again CDEX will only work when the multiplexed sound tracks are
split using the demux tool in digi TV.
I've found support at nebula to be excellent and they will guide you through
the steps if you want to try it.
Finally, I would prefer to send you star wars on a cd rather than sending a
100 mb file via the net, so if you email me off list with your address, I
can get it in the post within 24 hours. Don't worry about the cost as I can
send it articles for the blind.

Hi Stephe I would like the first part of star Wars. MP2 is ok. Does
anyone know of a way to take an mp2 file with audio description and convert
it to mp3. If I try this with Soundforge or goldwave the audio description
track doesn't play. Stephen, do you know how much slave units cost from
nebula.
Thanks
Paul
