Well. I'd say that it's a little too soon to worry.
However, there's a number of things to bolster numbers. Get into it with some people who will constantly come back and view the videos and give feedback; continue to produce content and find forums of people who exchange them with; chat with people who would watch the videos and bring them to them; and finally engage in making videos that would be part of contests or attention-grabbing events (such as other channels who take video replies and etc.)
The channel is just starting out and therefore very small. Right now it exists entirely on SEO (keywords and titles) and attracting attention from people just browsing. Therefore it needs to be brought out to people via avenues of marketing and/or community building.
This forum is a good start, but specific interest groups might be an even better place. Got a gaming guild? Got a circle of friends? Got a gaming forum that thou frequent? I'd say make sure those sigs are linked up, ply the wares, and seek feedback there, perhaps it'll pull the views up socially and get the channel over whatever hump it'*****.
