[vdr] Location of subtitles

Hi! (VDR version 1.7.10, Ubuntu 9.10)

I have "little" problem with subtitles.. Location of them. My TV is FullHD and to get nice menus I have set:

Setup - DVB Subtitle offset: 100

Setup - Plugins - xineliboutput - OSD Resolution: 1920x1080 Blending method: Hardware Scaling method: no Show all layers: no Dynamic transparency correction: Off Static transparency correction: Off External subtitle size: tiny DVB subtitle decoder: VDR

Problem is that 100 is bigest offset value what can be set and with that value, subtitle are about middle of screen (at left side of course) and not at foot area where they should be. If I change Blending method to software, I can set subtitles to right place with offset 70, BUT then text at OSD is awful looking.
