Tvheadend

Hello,
I have Synology DS210j and ITE9135 tuner DVB-T (in info screen/linux terminal identified as Zolid Mini DVB-T Stick or ITE 9135 Generic).
I have installed Video Station, checked for channels. All went well. Installed TVHeadend, choose contry / city (Poland/Warszawa), scanned for service. Found them all, however these services can not be mapped to channels, because they dont have names. The names are blank.
I can play direct link from service copied to VLC.
I can not play via TVHeadend server to my XBMC, because no services are mapped.
After restarting DS210j, I have to do such a procedure for DVB-T adapter to be seen in TVHeadend:
1. Start VideoStation from main menu (Video Station package is always running, but I have to activate it fro TVHEadend to see the tuner)
2. close TVH service
3. run again TVH service. Now I can see tuner in adapter list.
When scanned again all services are found, no names are given.
I can pres map services to channels button, however this makes nothing.

Please help.

Ps.
I attache screenshot from Geexbox TVHeadend from the same antenna. No problems there with services.
