Hi.

I received the product, I use it on openSuSE linux 11.4, kernel 2.6.37
I compiled and linked the code, no problems.

It works fine for unencrypted channels, both SD and HD dvb-s and dvb-s2
I use kaffeine and have astra 1, astra 2 and astra 3 sattelites


However, for encrypted transmissions, my mediaguard3 chipcard + certified
CAM does function only sometimes. ( I have legal card and CAM, paying for
it, no funny stuff !! ) the CAM is certified by Canal Digitaal, provider
in most of europe and works fine with inverto scena 5m sat receiver.


It seems to be an overflow in the software...
Please look at the excerpt below from dmesg, and specifically the last 3
lines.
It is a buffer overflow, apparently.

In first instance I do get picture + sound from crypted Netherlands HD
channel 1,
works fine.

If I change to other encrypted channel, it mostly fails with message as
below, but not always.
After failure of encrypted channel, Unencrypted SD and HD still works , no
problems with that. Once encrypted fails, it does not recover when
changing to other encrypted channel that worked before failure......

Please fix this problem, otherwise very good product.
I am willing to do some testing, if you tell me what to do.

hope to hear from you soon,

regards

rensg

Hello
What about a new driver v111118? Have you tested with Your CAM?
I'm affraid CI (CAM) not working correct under Linux.
Polsat Nagra don't work too.
We are stil waiting, and waiting for real support in this matter.

Hello,
I get the same error with mythbuntu 11.10 x86_64 with 3.0.0-14 kernel and latest driver (V111118) installed. I use two LNBs (Astra 1, Astra 3A) with simple DiSEqC switch.

I've tried two different CAM modules - MASCOM and SMiT with the same Skylink (CZ) card, both with the same error. The only difference is in the expected buffer size (SMiT 512, MASCOM 128), which is exceeded anyway.

I (am trying to) use built-in mythtv viewer, which shows (I suppose) progress of tuning and locking by shortcuts TLAMC - usually gets stucked on C (TLAMc or TLAM_), sometimes even earlier (Tl__). Practically it tunes one or two channels and then it's over, sometimes not even that. After removing CAM and restart mythtv I can tune free channels with no problem, even faster then with CAM plugged...

Here are two more errors from command

Any help appreciated, it's my money anyway...
Thanks.
