You might check on youtube to make sure you're downloading the absolute highest quality . I haven't really sought out 180/360 video though, mostly for that reason that it'll never really look good. Even if it was high-resolution enough the fact that your head is fixed in position really kills the immersion for me. Also unless the stereo separation of the recording matches your IPD the scale will look off. 

For lewd stuff, actually rendered 3d is the way to go. /aco/ has a thread about VAM for western shit, and /h/ has threads for koikatu and cm3d2, which both have vr support.
