# TODO :
# - offer to sort channels after
# - try to figure out country from locale ?
# - try to figure out tv norm from country ?
# - use Video-Capture-V4l-0.221 ?
# - reput kwintv and test it ? => still buggy it seems ...
# - configure kwintv and zapping ? => they've already wizards :-(
# - install xawtv if needed through consolhelper
