[Cin] Sorry, updated mpeg4 profiles again

[Phyllis Smith]

Andrew,
I just noticed that the flv_h264.flv output file is so pixelated (original
was 352x240) that I think it would only be useful on a small play device
(lots of those around in phones these days). And for some reason the
mpeg1_mp2.mpeg is now working so obviously I was doing something wrong
originally.
