Hello everyone! I'm from Argentina, and up to last month I've been using VDR 
1.7.262 with an ISDB-T USB adapter. It works really good, but the last week 
I've been trying to upgrade to VDR 2.2 and I've found a problem with ISDB-T 
cards: they are not supported.

As I'm really interested in using VDR, I was digging inside the code and found 
a partial solution for this problem: as ISDBT is the same as DVBT, I've changed 
the way delivery system is queried. My changes are applied in a cloned repo at 


That's the only change I've made. Now I can enjoy my fresh upgraded VDR 

I think a better refactor should be made, but for now it's working perfectly 
deployed as a docker container: 

If it works for you this way, I'll adopt this change in the next version.

Surely there should be a better implementation, since ISDB-T has several
tuning parameters of its own. But since there is no such signal here I can't
implement/test this myself. Somebody with the proper hardware/signal/knowledge
would have to do that.

I've tried to follow vdr code, and I think I shall add specific code to 
dvbdevice.c, specially:

  * GetRequiredDeliverySystem
  * cDvbTuner::SetFrontend
  * cDvbDevice::QueryDeliverySystems
  * cDvbDevice::ProvidesSource

That sounds about right.

Is there any developer guide for VDR so I can read it before trying to 
understand directly from code?

There's just the source ;-).
