can you implement an option to set up how big the streaming cache is? or is it handled by omxplayer?

You can set this via the advancedsettings.xml. I think I posted it a couple of pages ago.

I am using this in my advancedsettings.xml and now my Teletext is almost in sync.
XBMC need to fix so teletext is synced with audio/video.
With normal cache subtitles comes 2-3 seconds to fast for me.

<network>
<cachemembuffersize>262144</cachemembuffersize>
</network>

Hmm or it just works sometmies it seems maybe depends on channel.
This issue really shuold be fixed in XBMC but i think real teletext subtitle support in Enigma2 PVR addon maybe fixes this issue.
