[SDL] smpeg rewind

[obr at nri.cz]

Hello Bill,

	i don't know what version of smpeg are you using, but when
i played with it i found out, that it's not good at rendering
some parts of mpeg - when you seek on some frames it doesn't
jump there. I made some changes in the code, that could fix it.
The seeking code is different from playing for some reason (i'm
not an mpeg expert) so my change was to do it same way (what i remember 
it's about 2 yrs ago)
