Why not add the mythtv user to the sudoers file with the ability to
run nice (or if you're paranoid about security, nice --5 xine or
whatever your complete executable is)?
for example, add this line to /etc/sudoers (use visudo to edit
/etc/sudoers for security):
mythtv ALL = NOPASSWD: /usr/bin/nice
mythtv ALL = NOPASSWD: /usr/bin/nice --5 xine -blah -blah -blah
mythtv ALL = NOPASSWD: /usr/local/bin/my_script.sh
(replace mythtv with any other username, or %group for a group, or ALL
man sudoers for more info. This is a 'nicer' and more secure solution
than using setuid.
