Example: http://www.twitch.tv/jaybonaut/b/506635081

I have a 30/4 connection. Settings I use:

CBR on
Max bitrate 2500
CBR Padding on
30 fps
preset veryfast
CFR on
encoding profile main
keyframe interval 2 for twitch
no downscaling
AAC/128/44.1

Main Specs:
i7-3770K @ 4.1
GTX 680
16 gig DDR3

I am a noob at streaming and noticed on playback the constant hitching you see in the link I've included. Is there anything I could try? I've gone down to 2k max bitrate, no change, etc. Ask me anything as this is driving me nuts.

I had a bunch for today, I am not sure which one you want, they vary from 1 kb to 135 kb. This one was 11 kb.

Ideally we want to see a log file from a streaming session that exhibited the problem. You don't appear to have any performance issues from the log you provided, but you did have some dropped frames:

14:56:51: Number of b-frames dropped: 4241 (2.5%), Number of p-frames dropped: 4310 (2.5%), Total 8551 (5%)

Dropped frames could definitely cause the freezes/hitching seen in your VOD, so check out the suggestions at viewtopic.php?f=5&t=8870 and see if they make any difference.
