Do you watch that channel? If not, go to Configuration->Channel->Channels and the untick the enabled flag next to that channel and save.

The actual problem is likely that the "&" is a special character in xml and should be

&

You could try clicking edit on that channel and save the new name to be

A&E TV HD

There's already code which escapes those chars:

htsbuf_append_and_escape_xml(hq, channel_get_name(ch, ""));

Please, upload (attach) the wrong XML file.

Parse error in:
