I have found that programs on TVNZ with an & ampersand in the title cannot be chosen as nothing happens.
Ampersand is a special character in HTML and this will be what the problem is caused by.
In HTML, the ampersand character (“&”) declares the beginning of an entity reference (a special character). If you want one to appear in text on a web page you should use the encoded named entity “ & ”
Could this be fixed by searching for programs with " & " and replace the 3 characters with “ & ”
