There are generally two ways of watching matches online, as far as Poli is concerned.
The first and most simple one is by going to MyP2P. There you'll find out if you can watch Poli's match using a software program, most likely Sopcast (you can get it off the website), on match day. All matches in Romania are shown by GSP-TV 1, 2, 3 or Antena 1.
The second option is to go to a website like microbist.org, choose the channel which is broadcasting the match and make sure you have the sopcast plugin installed. Also, it's preferable to use Internet Explorer to watch the matches on this website.
You can probably also try to watch the matches on Antena 1, whenever they are the ones broadcasting it, or just go to http://www.favorit.tk/ and look whether the channel broadcasting it is anywhere among the available online channels. You may also try http://www.gecotv.ro/.
To see which TV station broadcasts the match, click here and check on the right hand side, under the league table, when and where the match will be broadcasted.
I hope this is sufficient info for everyone interested. If you have any questions, just add a comment and ask. Enjoy!
