Experiment regarding playback problems on Bravia TVs.

This patch experimentally reduces the maximum GF interval for
static content such as slide shows.

It does not fully revert the previous slide show patches as this
still allows the codec to code static sections only using GFs
groups rather than ARF groups or a mix of ARF and GF groups.
However, the maximum group length is reduced.
