[Q] Question regarding new adreno drivers for sony xperia neov

view story

http://forum.xda-developers.com – Hi there. I read on this post http://forum.xda-developers.com/show....php?t=1828902 about the new adreno libs and driver. I've flashed the zip file, everything went ok but the only problem was that I couldn't watch any video(mp4, mpeg, avi). That was the only glitch otherwise the new drivers speed up my neo v. Is anyone having problems with the new drivers running JB(I am on PAC-man rom JB-CM10). Any ideas-solutions? (HowTos)
