I watch most Sting away games on OHL Live. I've had a few issues in the past with the feed not even working and ended up missing the game. I sent an email to their customer care and never got a response, this has happened 3 times that I can remember.
So far this year I haven't had any issues.
As for the quality it's hit and miss and a lot of it has to do with where the games are being broadcast from. Feeds from Saginaw and Flint have been pretty rough. The person behind the camera is also a factor. There are 4 options for quality control, Best available, 2000kps, 1000kps and 500kps. Best available I find annoying depending on the connection. It can lag time to time. I try and use the 2000kps if it wont leg but a lot of the time I'm stuck with 1000kps which isn't amazing by any means but it is watchable from a distance (I run a HDMI from laptop to TV)
