It could be that your STB doesn't like the number of connections being made when you use Overnet/EDonkey.
The upload setting in the P2P software shouldn't be set to your actual upload speed, as you'll saturate the upstream & cause connection problems.
Try capping the upload in Overnet/EDonkey. [Have a look at

Also worth reading this thread through from the start (as your post has been merged with it).
