MythTV failing to add in 6921 card..

[manaesh]

Hi

I have brought a 6921.

I have had mythtv installed and running on a DVB-T card for 2 months without a problem.

I installed the drivers as per the readme:

I can scan via scan :-

cut

And get a conf file....

However - when trying to install into mythtv 0.23

When I add a capture card (DVB DTV v3) - can can select the new adaptor2 - but it says :

Frontend ID - Could not get card info for /dev/dvb - Subtype unknown error.

I select LNB as usual from the DISCQ options, and add the card..

I create a Video Source and then try to associate that in Input connections.

I try to click scan for channels - but get a "failed to open card error"

Clicking next gives me a "Programmer Error"

Loads of googling has not thrown up this error or any fix.

Can anyone help???

Many thanks

hi Mike,

the logs shows that the driver is correctly install and fully functional, which is double confirmed from your test with 'scan'. however, obviously the problem is MythTV configuration and it seems to me it's clear why: you select "(DVB DTV v3)", which should mean adapter that is using Linux DVB API v3 - your DVB-T adapter indeed uses API that is v3 compatible, but no any DVB-S2 hardware can use Linux DVB API v3, because that API version doesn't support DVB-S2 - in Linux DVB-S2 hardware drivers use Linux DVB API v5.x, which is also known as "S2API". so, please, check MythTV documentation how to configure S2API/ Linux DVB API v5.x compatible adapter in the application.

regards,
cody

For anyones info -

MythTV was not the problem - it was permissions.

It was the permissions on /dev/dvb/adaptor?/frontend0. Root owns them and the video group has read access, but everyone has no access.

We added in the current user - and we can now view the card and scan for channels....

Might we worth adding to a FAQ to save headaches!!

Cheers

Mike

Mike, thanks for reporting back the solution, i'm sure all customers that experience similar issue will benefit from that information.
