if command and conquer works then red alert 1 will be working too, what resolution did you choose in command and conquer? Did you try the same one in TS/Ra2?
Keep trying some more resolutions, it just depends on what your PC supports. The tiberian sun config which was added by the patch shows you a list with all supported resolutions, go through all of them until it starts up
CnC1 and RA1 will be working fine in window mode too, that's another way to bypass this error. TS and RA2 will not be working in window mode on windows 8 without flaws
