							Hi,

...
...
Since recently I have been using Skystar USB HD with my vdr
...
...
box. However I have some strange issues with 11817V on Astra 23.5E.
...
...
Femon reports that there is a lock and sound comes but the image is
...
...
completely garbled. I am starting to suspect that there might be
...
...
something wrong with the driver, because I have no trouble with the
...
...
other transpoders. Maybe it is the combination of fec=5/6 and 8psk on
...
...
the said transponder that is the reason for this. Other transponders
...
...
with fec=3/4 and 8psk are OK. The same setup with an HVR-4000 works
...
...
fine.

Kernel: 3.3.4

VDR: 1.7.27

Could someone who owns a Skystar USB HD and has access to Astra 23.5E
...
...
share his experience? Is this a driver issue a problem with vdr or is my card faulty?
...
...
...
...
If someone would be kind enough to test this with his/hers hardware, there is a FTA channel on the problematic transponder:
...
...
...
...
...
...
...
...
Planeta HD;SatelliteBG:11817:VC56M5O35S1:S23.5E:27500:1001=27:1002=@3:0:0:5410:3:3206:0
...
...
...
...

...
...
Any help would be greatly appreciated.

Hi,
...
...
few months ago on this transponder was nearly 30% of null PID packets
...
broadcasted, but now it seems to be much better (less than 1Mbps). Also
...
multiplexing of this transponder was not equal within time - there was
...
chunks of packets of PlanetHD multiplexed with chunks of other SD
...
channels mixed packets. Maybe the buffers for USB are not big enough to
...
memorize such chunks? But I didn't done measuring for some months, so
...
the situation may be different now.
...
...
You can see bitrates of this transponder at
...
http://www.digitalbitrate.com/dtv.php?mux=11817&pid=5410&live=70&... .
...
...
The bitrate of this channel is nothing special, with maximum about 11
...
Mbps, the peak of 20.2Mbps at 22.5. was maybe a joke.

Hi,
Since 20 Nov transponders 12051V and 12207V on the same satellite Astra 3B were switched to fec=5/6 and they also became unwatchable. Before the change they were 8psk, fec=3/4. Now they are 8psk, fec=5/6.
