yes, it's using a matrox card and doing mpeg decoding in software ...

yeah, that sounds reasonable - same here ;)
i have a nvidia (Geforce 6200) with passive cooling - i assume it could
do PAL interlaced on the RGB out ... but i havent tried it by now ...
as nvidia also has xvmc, i assume it can do hw mpeg decoding also - it
has s-video and composite out too - and is about 40 euros here in
austria ...
however power consumption - and heat dissipation - and space rises with
this ...
