manifest file missing ui_resolutions=hd

[belltown]

Problem

This channel does not work on SD TVs. Only part of the "Hello World!" text is displayed.

Cause

The manifest file does not contain a ui_resolutions entry. Consequently, the channel reverts to the default, which is ui_resolutions=sd,hd. The channel assumes a 1280x720 display. No scaling down to 720x480 takes place because of the presence of the default 'sd' UI resolution.

Solution

Add the following line to the manifest file:

ui_resolutions=hd
