all of Energy roms recently have had that problem (sinse March 30th i guess) for a long time, and the Energy ROMs chef is trying very hard to solve this problem, so dont be so worry, it'll be fixed in no time, and btw, have you tried the newest Energy ROM 24th, try it, maybe the problem is gone
Cheers, and in the mean time, if you want to watch vids on Youtube, u could you another Youtube app instead (search in Energy ROMs thread), or just using IE 6.0 and watch Youtube onl (by mobile web)
