Dear Vladimir,
I took a closer look on the CI-CAM adapter from Technotrend.
There is a 3.3V voltage regulator (LM1117 DT 3.3V)
Similar, on the AD-SP400 it seems to be also a 3.3V voltage regulator (marked 1084-33PE).
4046 board from Twinhan/Azurewave.
According to SMIT operation voltage for their modules is 4.5 to 5.5V
If in both cards the CAM takes power after these rectifiers
you cannot have a guaranteed operation.

Do you think SMiT will be interested in hunting for bugs in linux
drivers? These modules apparently work fine with any other hardware
(I'm sure professional ones do!)

Did you try to contact SMIT support ?

Didn't try Aston CAMs with mpeg4. But they do up to 12 channels of
mpeg2 perfectly well. With no problems at all. SMiTs that are for
8 services can do only 3 to 4 for me.
I think it's some kind of a driver bug because it begins working
after reinitialisation. Doesn't get hot. I have tried to call
Aston as well but with no success yet.

Dear Vladimir,
I read your post on linux-dvb list. We have an Aston Viaccess
Professional 2.15 CAM .
I read that you also use Aston CAMS. My question is whether your
Aston Viaccess cam can descramble H264 feeds or not?
We have tried on a PACE HDTV receiver and a Tandberg unit and it
does not descramble the H264 video pid. (black screen)
This does not happen with Viaccess RED cam.
On older Common interface adapters from Technotrend, the one for
TT Premium DVB-S card, there was a jumper for 3V or 5V cam
operation.
I assume the new CI adapter does not have such jumper. If it
still exist maybe it will be a good idea to switch from one
voltage to the other.
Another solution is to test whether it works or not for Irdeto to
use an Alphacrypt Classic CAM which, at least in theory,
according to MASCOM, supports Irdeto.
The third thing is to notice whether the SMIT cam gets hot in
operation. If it gets too hot maybe a fan similar to the one for
graphics card must be put near the Common interface adapter.
BTW. Do you have any e-mail address from Aston? I have tried to
contact them but there is no e-mail address in their website.
Best regards,
Dan Lita

Hello!
I'm using SMIT cams to descramble channels on TT S-1500 and TT-
S2-3200. After some time of normal operation SMIT cams drop out
and stop decrypting the stream. It needs to be removed from the
CI slot and reinserted to resume normal operation. Aston CAMs
have no such problems, but they don't support 0x652 Irdeto.
I'm streaming with vlc. Tried many SMITs (Viaccess and Irdeto).
Same problem everywhere.
Regards,
Vladimir
