#Exit mythfrontend and mythbackend
#Enter mythtv-setup
#Go to card options
#Select your DVB card
#Go to 'Advanced Settings'
#Select 'Recording Options'
#Check the box that says 'Record in TS format instead of PS'
#Exit mythtv-setup, and restart mythbackend and mythfrontend

====Garbled / very quiet sound regardless of channel====

'''Fix:''' set up the tv card to record in stereo rather than 5.1 audio.

'''Fix:''' 

#Stop mythbackend
#Run mythtv-setup

====Full scan does not pick up channel 9====

#Stop mythbackend
#Run mythtv-setup
#Select Option 5. Channel Editor

==== Channel 9 and GO! No Longer Record ====
After the new channel GO! 99 was launched, something hinky happened to the channel. If your Go! and Nine recordings appear to record, but don't actually write to the hard disk, you will need to run mythtv-setup and re-scan them.
