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:

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

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.
Hi,
bttv0: registered device video0 bttv0: registered device vbi0
And yet. If I try use Avertv a761 and PRV 150 with pvrinput plugin, I have vdr crash:
It seems that the driver for your a761 registers also an analog video device. pvrinput tries to open it and sends a VIDIOC_QUERYCAP to determine if it's a device it can handle. But the driver don't like it...
A dirty workaround would be to add the option "video_nr" and "vbi_nr" to your bttv-module (look at "modinfo bttv") and set the number to something greater than 16. pvrinput will only test the first 8 video-nodes (see global.h in its source if it's modified).
The right way is to look into the driver and test it if it crashes when you send the ioctl mentioned above.
Regards, Lars.
I tried "options bttv video_nr=17 vbi_nr=17". It works fine.
Thank you.
Remains to solve the 1 trouble, playing dvb-t.
Best regards.
