If you want to watch bangla tv's live from your PC I hav the solution, I am giving out some cool links so you can watch the common tv's up from your computer. Remember you need high internet connection to watch it properly. A broadband connection would be the better choice. How about 1mb or more. I use 3mb so I don't find any problem.
