fixed mediagen issue and tweaked url pattern

Added the mediagen device line to code. Not required for Logo yet, but does not hurt or cause any errors in the code and most likely this website will switch to the same method as mtv soon.

Also changed URL service pattern for video clips found two while tweaking the search that caused error. One was '/video/news/.../mgidnumber/...' format and one that was just '/video/.../mgidnumber/... format'. And both work new urls work with the URL service.
