[mythtv-users] Advice on mythtv setup needed

[drbob]

Hello,

I'm new here, I realise the questions below have probably been asked 
before, if that annoys you, please stop reading now :-)

I'm currently deciding on how to set up a mythtv system. I already have 
a headless debian stable machine (duron 1600) which I use as mail 
server/filestore. I plan to upgrade it to debian testing (so as to have 
qt3) add a couple of dvb-t cards, plus a 200Gb disc and use it as the 
backend. Frontend will be a dual boot windows/gentoo duron 800 system 
with 256Mb RAM and an ati radeon 7000. Will this be powerful enough?

I've been reading through the guides and the only thing I think I will 
have major problems with is connecting the frontend to my displays. 
Ideally I'd like to use dvi out to my projector at 854x480 resolution to 
get 1:1 pixel mapping, I would also like to use tv-out (which looks like 
it will be a nightmare to set up) for when I'm not using the projector - 
How does mythtv deal with non standard resolutions? Will it refuse to 
work at 854x480 or deal with it gracefully and does it support dynamic 
switching of the resolution (for when I want to switch from using the 
800x600 tv out to using the projector without restarting myth)? This 
would need myth to recognise that the projector is 16x9 so needs 
anamorphic output whilst the tv is 4:3 so would need letterbox output. 
Does anyone out there already have a similar setup?

Thanks in advance for any help.

regards,

drbob
