Hi,
Selon Patrick Boettcher <patrick.boettcher@xxxxxxx>:
Might be a mistake: Do you say that when you convert the data from
the old
buffer to the new agc-structure it works better? Otherwise I don't
see why
it changed.
I didn't try that yet. I wanted first to know your opinion on it.
I will try it this evening.
No it still doesn't help :(
As I don't have a datasheet nor a knowlege of the driver, I don't know
what to try.
With your mt2060 dongle, don't you see a signal strength loose between
old driver (with patched signal strength report) and new driver ?
Can't you attenuate your reception quality in order to check if you see
the same behaviour ?
I found a bug in the mt2060, the VGAG wasn't set to a correct level.
Now I get the signal level from the old driver, but there still no
picture...
The rate of the dvb stream reported by femon (from vdr is very low) :
0.5 Mb/s instead of 5 Mb/s.

PS : I attach a patch that add a init fonction from the mt2060 and
remove the .calc_regs callback as lot's of frontends check if the
callback is here but the returned value...
