Thanks Huevos for the suggestion
Optimize a discription as I called lamedb simply settings.
Fastscan: Add new AustriaSat Magyarorszag provider
Fastscan: Change providers list to list

So we have influence of the order within this list
Fastscan: remove obsolete import operator
Attempt to fix teletext subtitle timing

ttx pts and decoder pts may vary wildly causing eratic
display of ttx subtitles, even when setting delay parameters.

This is a first rough attempt to improve on this issue.
Avoid going to pathselect after the movielist is loaded

This change avoids going to the path selection screen when pressing the
movie key while the movie list is still loading.
Introduce auto fast scan functionality

At this moment auto fast scan is initiated when the box is 10 minutes in
standby. When a recording is running it will be retried once an hour as
long the box is in standby.
FastScan: simplify some code by removing a complete class
FastScan: also stop PiP when performing fastscan

This will guarentee that 'all' frontends are free to use for the FastScan
ServiceScan: Add check if session.pip really exists before deleting it
Fastscan: change auto fast scan enabled by default
FastScan: use standby screen for auto fastscan screen

So the clock will not disappear during the fastscan anymore and in
addition the power button will now also disable/abort the fastscan and
stay to put the box out of standby
Small fix for the VFD display of VUDUO2/ET8K/ET10K
Fastscan: correctly delete self.scan
FastScan: change method to del self.scan with normal fastscan

use the same method as done with auto self scan using onClose
Fastscan: also refresh servicelist when canceled and scan was complete
RecordTimer: Solve a type

chechForRecordings should be checkForRecordings
Ensure boot into standby after a power shutdown
Ensure that we do not start to standby after a GSOD (crash)

The chance that we were in standby during the crash is relativaly low
so I added this code in enigma.sh after enigma2 binary was stopped with
exit code 5 that means it did had a GSOD (crash)
