You definitively don't need sudo to use ivtv-utils. Otherwise something is wrong with you installation. Like I mentioned before in this thread, give
TV-Viewer a try. It is a complete frontend with many features. Be sure to install the latest development snapshot (0.8.1a1) or you may get the latest source code using my bazaar repo on sourceforge (similar to svn)
Code:
bazaar checkout bzr://tv-viewer.bzr.sourceforge.net/bzrroot/tv-viewer
This will create a directory "tv-viewer". Inside you will find the file README, open it and read it

After that've installed all dependencies just use
Code:
sudo ./tv-viewer_install.sh
Thats it, run the program with tv-viewer. Check the configuration first, then open the station-editor to create a station list. Now you can enjoy all features.
If you need any help you can join us, by using an irc client, on irc.freenonde.net channel #tv-viewer
Or you can use
