Thanks for pointing me to the problem. But for working it it was necessary to 
add these two changes more:

                       vpid = stream.getPid();
@@ -702,7 +703,7 @@ cFrameDetector::cFrameDetector(int Pid, 
   newFrame = independentFrame = false;
   numPtsValues = 0;
   numIFrames = 0;
-  isVideo = type == 0x02 || type == 0x1B; // MPEG 2 or MPEG 4
+  isVideo = type == 0x01 || type == 0x02 || type == 0x1B; // MPEG 1,2 or 4
   frameDuration = 0;
   framesInPayloadUnit = framesPerPayloadUnit = 0;
   payloadUnitOfFrame = 0;

Now it seems to works as on older vdr versions (with PES), but video 
discontinuities are still present on Spektrum (as on many other channels from 
other providers). On STB's these discontinuities are not present in video.

Thanks and BR,

Ales
  

I have tu confirm, that I used both patches and it now works-I get
picture. But picture has errors.

I made recording with vdr 1.7.7 and prewious patches.
I get picture with several errors. Here:

Hi,

You can also add one more case :

case 0x19: // advanced codec HD digital television service

Rgds,

Can you please post a tested patch that implements this?

Klaus
  

I found out that errors in picture is caused by decryption of channel.
With every new ecm I get error (break up) in picture. Interesting thing
is that packet UPC has  about 70 channels, however only several has
problem with decryption.

Can somebody tell me, how can I provide more debug info?
