My streams are freezing about once every 3-5 seconds, to the point where I can't watch the stream and enjoy doing so. It will lag on all resolutions, when no one else is experiencing this lag.
My speedtest.net ratings are excellent, with 50download and 4 upload.
My ISP is Time Warner Cable in Northeastern Ohio. I have spoken with them many times, cleared my TEMP folder, everything they had. After this still didn't solve anything, they escalated my case to a "Tier 3 Support" after seeing my TraceRoute for twitch.tv. I was assured that it was an issue on their end, and then when I spoke with Tier 3 support they told me it was in fact an issue with twitch.tv and quote: "Twitch.tv has a lot of problems. We never throttle our speeds.".
