Bug: Edit Channel List - Unable to unset SD Channel as HD

Hi,

It looks like I've come across a Bug in the DVR Web GUI.

Under Basic Setup, if I click on '# Channels' found in the tuners section:

Select Edit and select a Channel as HD and save the change:

I then find that I am unable to revert this change. Regardless of Browser used, if I unselect a channel and save, it has no effect. Channel still stays as HD.

I also noticed, that if I have selected multiple Channels as HD, I am then only able to remove them 1 at a time. Unselecting multiple channels and saving, results in only one channel being removed.

For the time being is there any way I can revert this HD selection.

Many Thanks,
Gary.
