This bug has been fixed. Also, newer version of this driver has been renamed from lgdt3302 --> lgdt330x ... This new version is in cvs and will be included in the next -mm kernel. This new version contains code that will allow you to leave both ANT and cable connectors attached to your tuner. The driver will select the RF input based on the demodulation selected. If you want to test out the new version of the driver without waiting for the new kernel, follow instructions for using the merge scripts located at: http://linuxtv.org/v4lwiki/index.php/How_to_build_from_CVS > Then, do a QAM scan, which should result in more channels found.

Is this one of the newer features found in the new subversion release of mythtv? I cannot find a method for this in my gentoo version of mythtv. Thank you for this HOW-TO. :-) -- Michael Krufky
