BBTV, before it's free but now we have to pay lol. i think bbtv is good, cuz it buffers very quick, and it plays anytime you click it, lol... it has news (everyday news like ch3 news that airs in thailand), lakorns, sports, asian movies, shows (daokrajai, etc), and etc. the quality is quite good, i think quality is better than obizgo. it's 7 dollars a month, cheaper than thaitv. only sometimes the lakorn is not update (sometimes 2 days late), but that just sometimes. the lakorn is not update as quick as thaitv.
i think thaitv is the best, but bbtv is good too.
i don't recommend doozija cuz there's not much and very unorganized in there... bbtv is good for ones who want it cheap.
