I use VLC player for APP and flash for TWR )) But yeah flash is not that reliable so it disconnects more often, but still works fine for most of the time

In regards to the B sector, for now maybe you could combine CTAF and 134.850 as a temporal solution? The thing is that 134.850 is mostly active during the evening (2130-2200LT), and there are very few VFR traffic at that time, so wouldn't affect listening that much as combining it with 129.925.
