[mythtv] [PATCH] amd64 (-march=k8) frontend crash with ivtv

[tommy]

The pointer manipulation in the two lines of code are incorrect for k8 
processors, they were causing the frontend to segfault on playback.
This hasn't been tested on a 32 bit processor, so if someone could make 
sure it compiles without warnings and works that would be great.

Cheers,
   Tom.
