Description
Since the merge of multirec brench into trunk, I am unable to change channels for my DVB-S source. My setup is ROTOR->2 PORT DISEQC->LNB1 & LNB2
What I found so far: 1) Channel tuning works for the initial startchan, but then it fails to change to any channel that is not on the current multiplex. 2) Switching to a channel on the same multiplex as the startchan works. 3) Switching to a channel on another satellite does move the rotor to correct orbital location, but does not lock the signal. 4) The "Rotor" portion of the Signal Monitor display in OSD does not move and stays at 0% when switching to channel on different satelite although as noted in 3) the motor does actually move

I fear it might be broken by [15441]. Please try reverting that changeset and/or applying t4473_v3.diff in #4471.

I'm pretty sure [15460] fixed it. Please reopen if it still broken.

- Running r15462 still does not resolve the issue. Log will be attached shortly.
- To answer your other question, yes the rotor will move and the tunning is successful after manually changing the startchan and restarting backend
- Log will be attached shortly

Notes on the log:
Channels 12 & 13 are on the same multiplex.
Channels 8 & 6 are on different satellite.
Mythbackend started on chan 12 (ok)
Then I switched to ch 13(ok)
then back to ch 12(ok)
then switch to ch 8 (no lock)
then switch to ch 6 (no lock)
then back to ch 12 (no lock)
Note: The rotor does rotate to correct orbital position, it's just the Signal Monitor that does not show any rotor movement and stays at 0%.

(In [15471]) Fixes #4477. Fixes tuning for DVB-S rotor setups.
DVBSignalMonitor got not deleted fast enough (might be leaking) DVBStreamHandler was updating the Rotorposition in the old signal monitor so only the first tuning attempt succeed and all further attempts failed
debugged with help from Mark Buechler
I'm going to need a 'mythbackend -v record,channel,siparser' log from the channel change.
Also, if you change the start channel in mythtv-setup to a channel on a different satellite and restart mythbackend does it properly tune to that channel?
