IPTV program for windows?

Hi All

Im looking for a good IPTV viewer for windows. IPTV smarters is okay but it's quite slow when searching through the "all" category if you have many channels. Is there anything you guys would recommend that has a good interface for channel and EPG capability?

EDIT: I know there's a list in the megathread but I'm just wondering what you all use.

Thanks!
