I released a fork of IPTV Stalker Plus, named IPTV Stalker Plus Lite (yeah, an oxymoron), in the stickies. The reason was that the 'stable' version 10.2.4 is not as reliable as 10.3.4 in connecting to the server, and to bring the fixes from couch potato's 'mod' were too difficult. For me, the important features in 10.3.4 was the filtering, but the other integration features were not useful, so I removed those from the code (vs. hiding them from the configuration).
There was a bug fix that also allows the channel number to show in the "Sort by Play Count" view.
Because the configuration of tags at the server is not consistent, you may need to click multiple times to get a channel list or a channel, when you get those server error messages. It just seems like there are fewer of those messages with 10.3.4 than 10.2.4.
