I've looked into my problem a little more and it's not the same as Steve's.
My issue is when recording with DVB, it detects a widescreen aspect ratio.
When this is played back the aspect ratio (16:9) is detected and used.
However due to the way my TV out works, (PAL/Geforce2MX/Svid->Svid) I don't
want to actually use this mode. What I want is to always use the 4:3 output
mode and the TV will stretch this to widescreen (16:9)
This gives me the correct aspect ratio tho it seems a bit of a backwards way
to do it.
So what I have implemented is an 'AspectOverride' setting, which, when set
will always output as 4:3 on that front-end.
Is this of any use to anyone else? would it be an acceptable patch? Is it
the right thing to do?
I think it's only of use when recording with DVB, as Steve says above the
aspect ratio isn't normally detected on recordings.
If it's of use I'll tidy it up, do the DB setup stuff and submit a patch.
