Enter the Anysee E30 C Plus.
This usb tuner is remarkable because it has had linux drivers for a long while and the cost of this thing is 130€ from new where I am from. I however did not pay that much. I bought it second hand for around 40€. I can say that after using it for a while that 130€ is highway robbery and the only reason they can ask for that kind of money is that the competition between dvb-c tuners is appallingly nonexistent.
The anysee tuner uses the modules
dvb-usb
dvb-usb-anysee
tda10023
dvb-pll
If the tuner does not show up after the modules are loaded and the anysee plugged in, restart enigma.
Automatic scan and fast scan does not work. So manual scan with network scan enabled has to be used.
I expected the tuner to be quite slow like the aldi stick, but i was pleased to learn that the anysee was just as fast as the internal satellite tuners.
To top it all the drivers also showed signal strength. My signal across every frequency was between 93-96%.
I thought i had found my solution, but with all things linux it never is what it seems.
The tuner was fast but with some frequencies all the channels were
broken.
I first changed cables since i thought that might be a problem. I went ahead and bought some quite expensive plugs and cables and hooked it up. It didn't make any difference.
After some searching on linuxtv.org i stumbled on
this.
Unfortunately, the DVB-C tuners/demodulators (Philips TDA10023) of at least these combo devices suffer for most of the time from jittery reception – i.e. artifacts and choppy sound throughout recordings despite having good signal strength.
Looks like the non combo device also suffers the same problem.
In conclusion. The device is fast and has had linux support for a while, however the aforementioned problem of jittery reception makes this product a DO NOT BUY for 130€. You might want to think about it if you come across one for 40€ but even then it is a hard buy.
After these two usb tuners the writing is clear for me. Dvb-c tuners for linux boxes are cumbersome and it is better to save the money and your time. Sell your old box and buy a new box with built in dvb-c tuners. In the end it is more worthwhile since it saves you a lot of frustration and annoyance.
