Tvheadend

You need several dev libs to be able to build TVH. Try running ./Autobuild.sh -t precise-amd64 (or -i386 if 32bit). That should try and install missing dependencies and build you a deb package.

Note: this is all documented on the wiki, see Building and Packaging.

Feels like I'm following you...

sudo apt-get install libssl-dev openssl

... should resolve those two issues for you so you can compile.

If you want to downgrade to a pre-built binary instead, try:

sudo apt-get install tvheadend=version

e.g.

sudo apt-get install tvheadend=3.3.484~g9370273~oneiric

... would install the beta version if you have https://launchpad.net/~adamsutton/+archive/tvheadend-beta installed as a PPA.

Now, the challenge might be to find a PPA containing the version you're after - I just checked Adam's stable PPA and that's reporting 3.2.34. You might have to compile your own.

I still wonder why you're getting problems, though, so maybe we can get some attention here from someone who can help if you recap the issue.

To Adam :
Ah yes I see now! Thank you. I am learning all of this Linux stuff as I encounter problems so sometimes I ask dumb questions hehe.

To Prof :
You stalker! ;P
I have managed to add the beta version ppa and tried v3.3.84 by my own! I had to manually "trigger" my adapter so that tvheadend see it. But then it did find the services, something which v3.2.34 could not do. So it's a step forward. The "map dvb to channels" button was greyed out though, but it was late and I did not have time to look into it so maybe it's my mistake.

To recap what is going in, I used to run XBMC 12 beta1 (with tvheadend v3.2.18) on a Zotac ID80 and my adapter is the Hauppauge WinTV-HVR-950Q. Everything worked fine (I could watch tv and use the pvr functions without a glitch) until I downloaded and installed the stable XBMC 12 Frodo, which runs tvheadend v3.2.34. From that point on, I could not see my adapter anymore in tvheadend until I ran a "scan -c" from dvb-apps. Then I could see it, but it could not find any services to map, so no luck. Yesterday I installed the latest beta, v3.3.384 and although I had to "scan -c" again, at least it found the services. So there must be something my adapter doesn't like in v3.2.34 I believe...

Anyone has any idea what's going on?

Little update.
Yesterday I installed Frodo beta1 which runs tvheadend 3.2.18, then manually remove xbmc and upgraded everything then reinstalled Frodo stable. At that point the upgrade had updated tvheadend to 3.2.34 and magically everything was working fine.
So my guess is that the lubuntu that comes with the Frodo stable iso is incompatible for some reason with my system.
Aside from that I don't know why it works.
Thanks for the help guys!
