That is the most convenient section for Prudent TV as Konkani is closest to Marathi though not the same. At the same time it is at the end of the Marathi section, at 1298 next to DD Sahyadri (1299), so it should be considered differently from ordinary Marathi channels.
Similarly Namma TV is a Tulu channel, not a standard Kannada channel. So its LCN is 1697. Sri Sankara TV is 1698 IIRC.
Regarding Housefull Movies, 330 is the latest free LCN available on TS. It cannot be put high up in the order.
