Hi.
I have Aver Media AverTV a761 dvb-t tuner, on bt878 and SP887x.
And 2 troubles with it.
1.
It works well with kaffeine, but does not work with vdr.
Kaffeine can scan and play dvb-t h.264 transponder in my area.
With vdr I can scan channels only, with reelchannelscan or wirbelscan.
When I try select dvb-t channel, I have message info: Channel not available!
In syslog when system start:

When select dvb-t channel:
vdr: [5047] switching to channel 271
vdr: [5047] info: Channel not available!
I use vdr-1.7.16, tried reel eHD, softdevice and xineliboutput.
The channels are NOT encrypted.
Anybody can tell me something about this?
2.
And yet. If I try use Avertv a761 and PRV 150 with pvrinput plugin, I have vdr crash:
vdr: [7166] starting plugin: pvrinput
vdr: [7166] registered source parameters for 'V - analog (pvrinput)'

I have this trouble when try load pvrinput + a761 without pvr150, pvrinput and avertv a761 do not love each other :-)
I understand that a761 should not work with pvrinput, but why crash?
Best regards.
