i tried using various torrents with different trackers but bitcommet cannot connect insted it finds Seeds with DHT…
i want to know that why such a good client cannot connect to trackes to find peers
And why bitcomet eats my bandwidth when listening to port…like 30kbps continuously
need an answer << << << << <_< 
Well, let’s see the possible causes…
1 - Your torrents are dead
2 - The trackers are dead/offline/too busy
3 - You haven’t established a static IP address for your computer
4 - You haven’t forwarded your listen port properly
… al in all, because you haven’t configured your BitComet (version ??)… <_<
How about you start by reading (and replying to…) here?

Bitcomet has no problem connecting to trackers or peers, if you are having a problem we would need specific details to attempt to help diagnose why.
ps. I answered the bandwidth question in your other topic.
