Does it work if you restart mythbackend?  Are there any error messages
in mythbackend.log?  You can get additional logging about the
recording process by adding -v record to the mythbackend command line:

root at mypvr:/etc/mythtv# cat additional.args
ADDITIONAL_ARGS=-v record

Then restart mythbackend.  Or from a command line, temporarily add the
extra "record" logging while mythbackend is running:

sudo mythbackend --setverbose record

and turn it off again with:

sudo mythbackend --setverbose norecord

I am not sure if sudo is required above - all the second copy of
mythbackend is doing is to open a connection to a port on the main
mythbackend and send it the serverbose command.  So it may not need
any extra privileges.
