I have tried various internet TV sites for BG tv with various/intermittent results... This one is new to me, found by google's ad-words thingy guessing my interests from where I surf to, and feeding me adverts based on keywords.
It is
http://www.neterra.tv/bg/ and is all in Bulgarian
As you can see from the subscriptions (абонаменти) page
http://www.neterra.tv/bg/aplans.php there is a FREE plan. Some channels are free (for a year? & след това? не знам!)
For example. today's BG news is here
http://www.neterra.tv/bg/show.php?id=811&bm=2
(sometimes the link fails for me when I have closed the previous TV window, sometime u get strange messages, but keep trying)
And there is a BRILLIANT feature !

(there was a picture in the frame when I captured it - honest !)
Yes - you can slow down the playback (and it keeps the speaker's voice pitch normal too!) and you can pause it, rewind it etc while you try and hear/digest the words (or look them up). It is a Windows Media Player videostream that works great on broadband... it may be useless on Linux, Macs or modem.
A valuable language learning tool.
