I may be wrong but this is not about gcc support, but you are disabling
optimized asm-routines. runtime-cpu-detection might be even worse.

They will be enabled if the necessary headers (libraries) are installed on your
system, you override the detection which causes confusion (whenever x264 is
updated) and/or doesn't work (for example for live555).

Just use ./configure (and add --enable-menu if you really need it but be warned
that is does not work with vdpau).
You may of course have to add the include paths and defines from your original
configuration, I don't know.

Could you clarify the refresh rate of your screen?
(Or do you mean I wasn't clear when I wrote "Unrelated to your problem"? I just
wanted to save you from future problems.)
