These entries do not correspond to VLC symbols that can be used
they do corrupt various variables like min/max bits
This also no longer assumes that there is a single non subtable
entry
Probably fixes some infinite loops too

The 1000 did result in the appearance of a never ending reload loop
The RFC mandates that "If the client reloads a Playlist file and finds that it has not
changed, then it MUST wait for a period of one-half the target
duration before retrying." and if it has changed
"the client MUST wait for at least the target duration before attempting to reload the
Playlist file again"
Trying to reload 3 times seems a better default than 1000 given these
durations

jpeg2000 overrides the global lowres variable with a lowres field called reduction_factor
ffmpeg -lowres X causes the reduction_factor to be set
ffplay -lowres X causes both lowres and the reduction_factor to be set
ossfuss sets only lowres
only the ffmpeg variant works. This patch tries to make the other 2 work.
Alternative we could just error out if things are inconsistent.
More complex restructuring should be limited to the master branch
to keep this reasonably easy to backport
