This looks really interesting to me-

I guess my question is if I give my dvr or that port the highest priority, what does that do to my wireless surfing GF who would be pissed if her browsing was slowed down, which can be kinda slow at times as it is. Has anybody tweaked these settings in their router and if so, how has the rest of the users been effected? And does giving the dvr mac address or it's port the highest priority even help remote viewing be less lagged? Lagged, meaning a bit sticky at streaming in high 30 fps settings over eight channels.
