I know the card itself works, I could use it to pick up FM transmissions using my android phone and USB-OTG.

This is the result of the scan on my rather immaturely named network (After trying to get this thing to work for 5 hours)

Furthermore, looking at the "stream" screen, the card always seems to show up and then vanish again .....

Have you tried the other testicle? Sorry couldn't resist made lol. but seriously..

Make sure you're not using mostly AUTO values.

Make sure you have set: Freq, Constellation, Transmission mode, Bandwidth and Guard interval, without these tuning may fail

Ive tried using the following resources to try to add the frequencies manually:

https://tvheadend.org/boards/4/topics/10171
http://whirlpool.net.au/wiki/digital_channels
http://ozdigitaltv.com/transmitters/NSW/67-Kings-Cross
http://manlyelectronics.com.au/products/av/digital_tv_transmitters_sydney_northern_beaches.html

Scanning failed, even when adding the frequencies manually (I live in Sydney).

I've also tried installing w_scan and trying to see if I can make a list for dvbscan.

w_scan -c AU -X > channels.conf

Returning the output of:

Info: no data from SDT(actual)
Info: no data from NIT(actual)
dumping lists (0 services)
Done.

and a 0kb file.

I also tried installing kaffeine, and me-tv, both of which didnt pick up any channels.

UPDATE, Im an idiot:

Turns out the reason nothing was working (other than FM radio on Using an android OTG Application, was due to my room having Dysmally poor signal strength.

I took my laptop downstairs and connected it to the amplified Areal Jack, and TADA, it picked up all the channels.

Can a mod/admin please mark this thread as resolved? Cheers and thanks for your time in trying help anyways

:D

Yeah those RTL sticks are really bad with poor signals..

Also nice plant..

I presume the conclusion is that your signal was as much bollocks as your network, then... :D

lol. I like everything to be wired but there wasnt any ethernet near the TV. Also dont pay too much attention to the shrooms at the base of the plant d:
