How to cron a script?

[kinka]

Hi everybody. I've done a script to download the news from the website of the national italian channel. Because I am living abroad and do not have the satellite, with this script I obtain the link of the latest news (that changes everyday, that's why the script is handy) on the website, and with a great program mimms save the video on the filesystem. I have installed two jobs in crontab, one that runs at 10 p.m. that saves the file, the other one that wakes my up at 8 a.m. playing it. But that's the problem, if I type on the command line:

[diego @d-lap:~]$ gmplayer /home/diego/dowload/mimms.wmv

everything is fine, but if I put the same instruction in cron I can hear, but I cannot see the movie. Why? I am not running any screensaver if this can help. My crontab looks like this (crontab -e):

# m h dom mon dow command
00 08 * * * /usr/bin/gmplayer /home/diego/download/mimms.wmv

Thank you everybody that can give me useful information.

This is only a guess. When something is run in cron most people don't realize that their environment isn't set up like it is when they log in. In this case I suspect that environment variable DISPLAY isn't defined. I'd say write a script to define it and then run the video and see if that helps.

DISPLAY=":0.0"
export DISPLAY
/usr/bin/gmplayer /home/diego/download/mimms.wmv


Also, you may not have a screen saver but do you have it to lock screen?
