Pioneer XV-BD122B

Hi!
I got home theatre Pioneer XV-BD122B.
I'm using it on generic DLNA profile becouse there's no profile for it.
It works fine, no sub transcoding needed so i removed sub transcode form dlna profile.
The problem is that display aspect ratio in no good, it streches to full screen. (1920*800 to 1920*1080)
Tried to fix but didn't succeed
Also got a sony bravia TV witch transcodes subs, added sub transcode and it works fine.
No aspect ratio problems.
Need help! Thanx!
