Tvheadend

Hello,

last week I updated TVHeadend to 3.4. Since then it acts very slowly when using TVHRemote and starting XBMC.
When I open a channel XBMC tells "Connection lost" Timers are recorded fine even with 4 Tuners.

OS is Ubuntu 12.04 server.
XBMC is running on Raspberry PI with Raspbmc

Hardware: D945GSEJT 2GB RAM
Tuners: STB0899 USB DVB-S2
STB0899 PCI DVB-S2
Philips TDA 10046H DVB-T MiniPCIe
Wideview USB DVB-T

All Tuners working fine when recording but sometimes failing when subscribing directly from my Desktop PC (state:testing)

Any help would be nice!
