Another advantage of HLShd was that there was no HE-AAC when the audio
was 96kbit/s. HVF has used HE-AAC with 96kbit/s audio for some time,

A couple of years ago there were problems with HLS and there was
speculation that we might have 50 fps HVFhd and DVFhd as the only HD
modes. At that time I wondered if it would be feasible to drop every
