Try it without the redirection and see if cron mails you anything.
You might even do

0,30 * * * * echo 'starting' && /usr/bin/tvguide.pl && echo 'finished' 

so that you're sure to get some output.

Perhaps the script depends on the value of some environment variable
which is set in your shell but not in your crontab.
