These are my upgrade notes I promised from my last post about MythTV. Please read that first before going through these, as they have information you might need pertaining to my MythTV setup. These are just notes I made during my upgrade from Mythtbuntu 8.04 LTS to 10.04 LTS. The notes were just for me but I thought I would share them. This is not a how-to! It leaves out many steps so don't think it will help you get your new MythTV box setup. Enjoy!

# Upgrade MythTV from Mythbuntu 8.04 to Mythbuntu 10.04. MythTV 21-fixes to MythTV 24.1 fixes.

# Call comcast after getting HDHR Prime and get cable card added then ask tier 2 to send a grandslam hit or a cold
# hit also called a DAC Init "hit" to the device. Channel encryption will not work correctly if this is not done.

# After or during install of 10.04 in Mythtbuntu Control Center use settings
