I would agree with what Wingnut said about the gears possibly catching each other. You may want to lower the gear on the motor a little bit so the teeth of the larger gear do not hit the hub of the motor gear.

But my first impression is the speed is too high. Are you using the LCD to advance the extruder in the videos? Do you have the drivers set to 1/16th stepping (little jumpers under the drivers on a RAMPS board)? If they are set to 1/16th are they actually working in 1/16th? Are you using my version of Marlin for Tantillus? You can try running it slower from a host program like pronterface. If the speed is the issue we can then figure out why and how to fix it. Once it works in partially check your E steps per mm and fix them. Once they are correct it should run at a different speed. Be sure the filament goes through the extruder without any obstruction other then the hobbed bolt. If it does not run a drill through the holes into the start of the bowden tube.

To get the plastic to stick your best bet is to wipe the tape with acetone or 99% rubbing alcohol. Also you can scrape or sand the tape lightly.
The first couple of test prints have skipped steps and could be that need to up your stepper current just a little bit. Or maybe your x/y gears are loose. Or maybe your bushings are too tight. It also looks like it is only on one axis.
It also looks like either the flow is too high or maybe the the temperature is too high or maybe just because the fans are off. Either way I would not worry to much until you get past the skipped steps.
