If you like Tvheadend and use it a lot, why not make a Donation
Donations are made to Andreas, who manages the account on behalf of the project.
The money is used for keeping Tvheadend related infrastructure going (such as this website) and also for buying test kit for development/support.
Please remember that Tvheadend is a spare time project and that the time available for development varies a lot. We would appreciate if you think of donations as a way to express your gratitude of what's already been done, rather than a way to pay for features or bug fixes in advance. We all have families and day job's which are both (obviously) given priority over this project.
