It's long time ago, that you could view the bulgarien channels on thor.
2 or 3 sends their free-to-air, also Fan-TV on 16° east.
I'm looking Planet TV on Hellas-Sat 39° east, but this and the other channels are encoded in irdeto2 and only to see with an original card of bulgarsat.com.
You can buy the card in bulgaria for 210 Lew ~110 Euro/Year
