From thread:

When changing channels, only the first number typed/pressed appears on the screen, but the correct channel appears.

h4. Steps to Reproduce
From thread:

For example, if I want to watch channel 51, I press "5" followed by "1" on my remote. On-screen, only "5" appears in the OSD (instead of "51"). A second or two later, it correctly switches to channel 51.

h4. Additional Information
According to the thread, http://forum.team-mediaportal.com/bugreports-74/only-first-pressed-channel-number-appears-osd-104431/#post830116 , this is regression from 1.2.1
