You can fix the position of TeleSub and DvbSubs by changeing SubtitleDisplay in skin.xml placed in usr/share/enigma2/<skin>.
This should be changede to.
<screen name="SubtitleDisplay" position="280,110" size="720,576" zPosition="-1" flags="wfNoBorder" backgroundColor="transparent"/>
hhehehe
This is fix I have make and use for my HD skins longtime ,
with Gusax fix we have now good txt subtitles but if i use this old fix for DVB subtitles position
in HD skins we have limit in title size 720x576 and this can make problems if subtitle
text is to long like in txt subtitles we can use 1280x720 format and longer title txt.
This is not so big problem for DVB subtitles (small font size) but is problem for new
bigger font size for txt subtitles.
Ok.But now with this latest TXT subtitles fix I think we can use or not ?? both coding in skin.xml
one for txt subtitles and another old one for DVB subtitles.
I hope DMM can find time to look in to DVB subtitles problems on some channels
we have no DVB subtitles decoding ,subtitles font size is to small for HD formats
and position of subtitles is not posible to config 100% in HD formats (1280x720)
