[linux-dvb] TechnoTrend 2300 DVB-C, does it work?

[Bas v.d. Wiel]

Hello list,
Because of my troubles with a TwinHan Mantis 2033 based board, I'm 
looking to buy something else that actually does work. I was advised 
that a Technotrend 2300 DVB-C + CI-module will work with Linux. This'll 
be the second time I'll be spending over 150 euro's on video hardware so 
I'd like to be sure: does this combination work with Linux, and MythTV 
in particular, to view encrypted channels?

Bas

Bas, I'm waiting for the working CI Interface on the AD-CP300 (2033) 
card as well and I hope
the CI/CAM is going to work by summer.
Besides can't watching encrypted channels the card has worked perfectly 
over the last 11/2 year.
I use it with "vdr-1.60" and "xineliboutput".

The TT-2300 (and the identical card from Hauppauge) are the cards I have 
used over the last 5 years.
I still use it for watching encrypted channels (i.e. when the Twinhan 
card is useless).

CAM:           Alphacrypt-light
Smartcard:  Card from "Kabel Deutschland".
Software:     vdr-1.4.7 with tvtime; I have no idea concerning MythTv.

Ciao Ruediger D.

Hi Ruediger,
The AD-CP300 is exactly the card I own right now. I haven't been able to 
tune this card to a single channel yet, using whatever version of the 
Mantis driver, even though the card functions perfectly using Windows so 
the hardware is OK. My assumption is that a working Mantis card should 
be able to at least detect the channels, even if it's unable to decrypt 
them. I'm using the right frequencies, symbol rates and QAM-settings for 
tuning. They come straight from the working Windows side of the system, 
but nothing is found at all. I only receive a long stream of tuning 
failures using scan. I have time to wait for the Mantis driver to 
mature. On the Windows side of things MediaPortal is more or less ok. I 
just very much prefer to use Linux for my HTPC (or any of my systems for 
that matter).

But, if I understand you correctly, the TT2300 allows you to watch 
encrypted DVB-C under Linux, right?

This is strange, and as said already, my card tunes not only perfectly, 
but also fast. Channel switching is less than 2s!

Yes! By the way, do you have just encrypted channels in Netherland?

Right!
Obviously, you need to by the TT Premium 3.5" CI.

My first CI was from Hauppauge. Later I bought the TTs from

http://www.dvbshop.net/index.php/cat/c19_Technotrend-Zubehoer.html



One sentence about my experience with DVB-C:
Often, the true carrier frequency (fc) deviates significantly from the 
specified one.
For example:
Assume you have a channel (some people say "transponder") where fc is 
supposed to be 113MHz.
In my area (Hamburg), the true carrier frequency is approx. 112.3Mhz. 
Thus, the deviation is 700kHz.
This resulted in strong distortions, actually you couldn't bear this 
more than a minute with Linux.
The Windows driver could cope with this (after you switched channels once).
It probably uses different parameters for the PLL-locking mechanism.
However, in recent kernels (2.6.22.x) this is not problem anymore.

For the TT-2300 I used to apply a patch for (i.e.,against) it from

http://www.vdrportal.de/board/thread.php?postid=582559

I DON'T think you have a similar problem with the Twinhan card.
It is just an example for reasons, where you wonder why Windows works 
and Linux not.
I suppose the developers from, lets say Hauppauge, where aware of this 
strong frequency deviation
and designed the driver accordingly.

Below is just my scan command and the output of it.

yes, that was reported by countless people, but I'm not there.

This was only one of the reasons to ask Manu to stop advertising the new
expensive stuff that hard in Europe. The same goes for free S2. It is
nothing more than some blown up "muppets" show you get for now, at least
in Germany.

The work is fine, but people need to know how far they can get with it
on their place for now.

Results about pointing to it are known ... ;)

Cheers,
Hermann

I can confirm this. Almost every channel is encrypted apart from a few 
apparently random exceptions. I can watch NL 1 and Comedy Central FTA 
even though they're completely unrelated and Comedy Central is even part 
of an optional package if I recall correctly.. strange. Many radio 
channels are freely available though.

Last night I made a couple of new attempts, recompiling the very latest 
mantis driver on my Debian box. The card gets detected properly, as 
usual, but now I notice something new. I get an error message: DVB: 
invalid PC card inserted :(

I assume that has to do with the Alphacrypt I have installed in my 
Mantis board? I have yet to pull it out and test again but so far, with 
the Alphacrypt inserted, there's still no result whatsoever. After some 
loud protest from my girlfriend I had to give up, reboot into Windows 
and let her watch her favorite detective.. So frustrating!

Thanks for everyone's help so far though.

Bas

Not true. I can get around 40 channels unencrypted including Nederland1, 
Nederland2, Nederland3, BBC1, BBC2, Net5, SBS6, RTL5, Veronica etc. 
Basically, the ones you can receive for free over the air.

I have this same tuner card, and can watch these channels OK in MythTV, 
and I don't even have a CI + CAM (yet).

My cable company is Caiway, if that matters.

Hope this helps.

This matters yes.... Both UPC and Ziggo encrypt most everything....

I use a TT-2300-C, CI and Alpha Multicrypt  and a TT-1500-C, CI and second 
Alpha Multicrypt under vdr-1.6.0.

To be honest, I think the budget card is better.  The FF 2300 doesn't 
reliable do multiple decrypt, and I'm currently getting some weird problems 
where the card will decrypt some and not all channels in the same boquet. 
This might be to do with the CI or CAM, but right now I'm wishing I'd bought 
2 budget cards!!  At least I'd be able to support HD on both!
