I've finally got an IPTV setup working after writing it off as not possible, so I am loath to complain...much. The issue with the channel guide I can deal with (decided not to futz with the channel mapping after seeing the problems folks have been having with that part). A lot of the guide is incorrect some of the time, and the DVR functionality is still a bit too unreliable to be of much value... but what's really bugging me is how sometimes a channel will just get stuck in a loop where the same few minutes of content will just repeat in perpetuity. It doesn't happen when I watch through the IPTV provider's native web-player, which is why I'm thinking it has to be something related to Emby.
Anyone else experiencing anything similar?
