Yep - originally I thought I /needed/ to use the 'NEWSTRUCT' driver, but I
since found out my tuning wasn't exact enough and the 'normal' driver would
work. The frequency tables on

http://www.dtg.org.uk/retailer/tx_details/-tx_indx.htm

Only give to the nearest MHz, so there was me plugging in "754000000" Hz
into 'dvbtune' and getting absolutely nowhere.

It was only after several hours that I discovered the broadcast frequencies
in the UK are +/- 167kHz... so when I tuned to "754166667" Hz, the whole
thing suddenly lit up and I got perfect pictures...

Note of course, you local transmitter might end up being '753833333' Hz
instead, etc.

I'm currently using this driver:

ftp://ftp.cadsoft.de/pub/people/kls/vdr/Developer/siemens_dvb-0.9.4-2002-06-
23.patch.tar.bz2

This is the driver that Klaus (VDR author) reccommends for use with VDR.. so
you'll have better mileage if/when you write to the mailing list if you use
this driver.

and this VDR:

ftp://ftp.cadsoft.de/pub/people/kls/vdr/Developer/vdr-1.1.12.tar.bz2

(1.1.13 is released in the same directory and will also work =)

I haven't got that far yet :/ As soon as I hit 'Record', the picture freezes
for several seconds. I haven't tried sending the recorded file directly to
the dxr3...

If I try to replay a recording from within VDR, VDR segfaults :/

> And can you watch live programmes OK?

Yes, this works perfectly, with on-screen "now and next" programme info and
everything.

Nope, but the authors are on this list - they announce new versions of their
DVD-player plugin, so I'm guessing they do the same with the Dxr3 one. It
(and other plugins) are linked from

http://www.cadsoft.de/people/kls/vdr/plugins.htm

Yes, you'll need a fair bit more than 420Mb to do any serious recording...
VDR spools the direct broadcast MPEG2.. that runs at 9Mbit/sec for most
channels (BBC1 gets 15Mbit/sec!)...
