Yes, with --disable-sse2 all videos are playing fine. But following
warning always appears:

[swscaler @ 8ef4020]Warning: data is not aligned! This can lead to a speedloss

I've enabled debug output for swScaler() function, here is an output:

First two calls were made with unaligned source buffer, but the rest
calls are with 16 bytes aligned source buffer.

gcc 4.2.2

Thanks!
