PcTV Rave: how can I tune for channels?

I have a Pinnacle PcTv Rave card which has no tuner. There is a viewer for windows which includes a tuning function. But it seems the actual card doesn't have a tuner (or no driver for it in linux). I tried to install alternative drivers in Windows in the past and couldn't get past this step. I can watch tv through motv, but I get the channel which was last viewed in windows. I tried setting the prefs in motv, for tv norm and frequency, and then use the scanner but it gives a bunch of images from the same channel.

Ie. tuner set to type 4, which is..

type=4 - NoTuner

Ok I dug up some info on this from when I tried to get it working.

IIRC the tuning part is taken car of by the tuner module. (Kinda logical, no?

) The bttv driver is supposed to detect which tuner the card is using and load that. This is obviiously not happening for you (or for me either for that matter)

The problem could be either with
1) the tuner autodetecion code
or
2) there might not be any support for that specific tuner...

Oh BTW, Norway and Sweden use PAL B/G http://www.stv.se/stv/homesite.nsf/78667a69c23ab667c1256afe0045e4c9/6ff7f95ce6d00c27c1256b010072a076?OpenDocument

This card definately has a tuner. Probably from Temic but who knows things change :-/. The easiest way to find out would be to take it out and look at the chips. The tuner chip is probably from phillips or temic and would say the model which you could match to cardlist.

My prefered method is guessting. But only because I hate screws. You will probably get better results if you find the exact model. However tuner type=0 might work. I have seen ppl with the PCtV Rave who have claimed to have 3,33, and some others. Its so hard to tell cause they design for so many different tuners (because of different signals in different countries). Two different revisions for the same signal type might even use different model tuners. Although i don't know if this is the case with your card.

Good luck.

Thanks a lot, I'll try to have a look at it.

Another question is how do you set the tuner when loading the module? Someone suggested a line in /etc/modules.d/options but that had no effect here, dmesg still says tuner is type 4 (no tuner).

/etc/modules.d/options

Here is what the card looks like, any idea what tuner I might have?

If you are still having problems, try to download the latest bttv drivers and use them instead of the kernel supplied drivers.

i have the same card. i've got it working under linux for 2 years now. relevant part of my /etc/modules.conf looks like this:

I'd use this code.

Well still nothing, I tried all the tuners in the cardlist.

I also tried the newest bttv drivers (0.9.9) but that made no difference.

I loaded each one with insmod bttv tuner=x and then tried tuning in motv, either that or the channel scan. Didn't get a damn thing.

Wow, have you tried contacting Pinnacle Systems about what the tuner is? :-/ I can't really think of anything else.

Their support is crap. When others have asked about drivers for linux in their support forums, the pinnacle crew just ignore them...

To bad they have this big RF shield over the tuner... Hmm, I have an idea. Lets flip a coin. Heads you rip your RF shield of and tails I don't rip mine off. That way we'll find out what chip they are using

Do you have a link to their forums?

Has anyone gotten this card working with PAL B/G ?
