SMTube 16.7.2 is behaving strangely of late. This morning I encountered two search failures.
First I searched for http://www.youtube.com/watch?v=POk-uOQSJVk and got http://www.youtube.com/watch?v=AbRdPlfi6es as the first result, not exactly what I searched for. In fact, the video I searched for didn't appear in the results list at all! At least the results were related to my search. When I clicked on the NEXT button to see more results, however, SMTube crashed and the window disappeared!
Second I searched for http://www.youtube.com/watch?v=OP6dc_n-oo0 (Clinton Cash) and got http://www.youtube.com/watch?v=9pKwOLt3Ix0 (something about UFOs) as the ONLY result.
Youtube-dl was able to download both exact video IDs that SMTube could not find.
On top of these problems, SMTube doesn't seem to work through VPN service. When I launch SMTube with VPN running it never progresses beyond the 10% mark in the status bar. I'm pretty sure older versions of SMTube worked through VPN.
