I'll try to sort out the most appropriate method, I'm away on business for
most of the week so hopefully at the weekend. I applied for an account to
push but perhaps that wasnt what I was meant to do!

For the moment I set an encoder type ==...._TV_OUT, I'll set up a struct to
contain the tv properties and put this in the sdvo priv.

Sounds good, were you just commenting or can I take a look if I have time?

I have to admit I dont fully understand where you're comming from on that
one. Are you talking about TV aspect ratios? Can't quite remember the
relavance of square pixels

At the moment using the very old modesetting driver, I get xine to choose a
modeline which has the closest refresh / resolution to the video stream.
However with tv out this would not work properly as the tv format would need
to be adjusted also (and possibly some other output properties).
Is what you're saying above that the tv output / format should be fixed i.e.
PAL / NTSC / 720p etc. and the chosen resolution should be scaled to the tv
format? (or have i miss understood)
Ideally I'd still like to be able to dynamically adjust the tv format to
match the correct display resolution / refresh for video playback.
I've been wondering if something like the following would be possible.
mode 720x480 at 60
mode 720x576 at 50
The collections could be brought up by name and turn on and off the correct
displays set appropriate output properties etc. It should then be possible
to create a mapping between video stream types and link them to the
appropriate collection above (the user can configure what they want)?
