Fair enough.

I'm not at the machine at the minute, but this does sound about right.

Great.

I'm using 2.6.22 from ubuntu, so I won't have that support.

It was sold in an Aldi or Lidl (can't recall) in Ireland which while not
the UK is a very nearby market and likely to have similar stock.

I'll see if I can pluck it out of the machine and take a photo.

The radio does work.  There was a remote with it (which I never use, but
anyway).  When you ask what tuner, you mean a chip on-board, right?

I am using PAL.

I'm able to get sound from it using alsa or oss or alternatively take an
audio line out.

I guess I'd better get a camera to it and give you some more info.
