1. At the end of the video I got my cellphone closer to the screen and it is very clear that the time is 20.38
2. I don't see why there would be any problems with a player using a controller from the same company (Sony), the controller is not giving me any advantages. And if there was a doubt about wether is allowed or not, it would be up to the creator and founder of the track to decide, which is me. So I say it is allowed.

I would say using a controller to play the Vita is in the same vein as using an A/V output on a handheld to display it on a TV. That was debated once (that I saw) on a PSP submission as an "unfair advantage" but was ultimately accepted.

Anything that's first party and designed to work with the system in question I have no issue with. I am but one adjudicator, and I don't mean to say precedents should stand whether good or bad when extrapolated to additional areas of consideration, but considering that the console permits the use of controllers I would need to see some real proof that this provides more of an advantage other than preferring another controller to the buttons on the handheld.

I'll be voting yes if none such proof can be provided that there is some unfair advantage gained here. There is precedent for using a variety of controllers for consoles (see Sega Genesis controllers on Atari 2600 which is fine by me too, or using one of several remotes like the WiiU provides for where any of the first party controllers like the Wiimote or the WiiU gamepad or the Classic Controller can be used) and there is precedent on handheld consoles that controller and video configurations are discretionary (PSP video out to TV, using either a GCN or the GBA itself to control the GB Player on GCN).
