Whilst hardly intuitive, it works well and, once you've used it a few times, makes tuning a breeze because you can do everything by editing a text file.<br></div><div><br></div><div>Regarding multiple transmitters and long scan times, the usual advice is to first prune your transports ("Edit Transports") to match the multiplexes for your region as shown by <a href="http://www.ukfree.tv/transmitters.php">http://www.ukfree.tv/transmitters.php</a>, then always delete all channels before scanning using "Scan all existing transports".</div><div><br></div><div>You can then use mythupchuk to delete channels, fix channel numbers/names, xmltvids, visibility etc via a text editor.
