You can't get slow motion through /dev/ost/dvr. This device assumes
that it gets the data from a realtime source like a webcast or a
satellite transponder. Thats why can set filters on that incoming
stream just like it came from satellite. If you want slow motion you
have to feed your data as a multiplexed PS/PES into /dev/ost/video or
as separate PES into /dev/ost/video and /dev/ost/audio.
