I am not sure if I understand correctly, but if this 
were only about full-range vs video than you can use 
swscale for conversion.

I suspect though that either stride or the source 
pointers are not set up correctly, I can only 
suggest you debug them to see if they match 
what you expect.

Please do not top-post here, it is considered rude 
and please set your mailer to text-only, your mails 
are difficult to read.
