Since sources are limited to about 500 channels, and I am finding that most IPTV providers provide XMLTV Guide data in a single file for their entire offering, it would make sense to allow the creation of global XMLTV Guide datasets which can be set via a drop down list in the source configuration. This will eliminate the need to specify the same guide data multiple times, and thus not having duplicate data within the database.
Othewise, new user to the ChannelsDVR software, and am loving it....
Cheers.
