Apparently, there was a recent change to dvb_register_adapter adding the adapter_nr as argument. In the most recent kernel (2.6.25.3), this is already updated so everything should go fine (without the modifications I suggested).
Tutorial is almost done, currently building a new kernel to see if everything is ok.

[edit]
ok, never mind, came across the same problem.
Let's see how we can fix that

Ok, found the solution:
You should apply this patch.
The discussion about it can be followed here.
You should also add a symlink from include/linux/semaphore.h to include/asm/semaphore.h
For some reason, they changed this include during clean-up. I asked why, but for the moment it's better to add the symlink then to edit the code

Currently building my custom kernel, if everything goes fine, tutorial should be up later this afternoon.

Thanks for your effort bbackx! Looking forward to try it out soon.

Found out there are some troubles with this patch. I'll try to make a decent working patch.

[update]
Starting from a clean kernel-source, you have to apply three patches:
First, the one that adds the actual driver.
Second: http://firedtv.bbackx.com/patches/bback ... date.patch
and third: http://firedtv.bbackx.com/patches/bback ... bers.patch (!!patch based on 2.6.25.3 code!!)

Copy semaphore.h, semaphore_32.h and semaphore_64.h from include/asm (or asm-x86) to include/linux to fix some dependencies (don't know yet why they changed that).

You should also disable support for DVB USB devices and you're good to go.
Currently in final stages of building the kernel, should be able to boot within minutes and if everything goes fine, the howto will be on-line

[update2]
grmbl, forgot a patch
http://firedtv.bbackx.com/patches/ieee1 ... ding.patch
Hope this is the last one...

Well, the code isn't called beta without a reason
I found a null-pointer, meaning I'll first have to found out what's going wrong because I don't think you'll like a crashing driver

does this driver work with the S2 cards at all, or dosent it?
can you use it with mythtv?

How in that case?

Not yet, it will in the future, but for the moment it's not yet known when.

I currently have a FloppyDTV card, I am trying to use it with Mythbuntu, but up untill now, it doesn't work at all.

Do I need these drivers? As the card communicates via FireWire.

Yes. There are no drivers for Floppy/FireDTV cards in the current Linux kernel(s) by default, so this driver is a must.

Thank you.

Now, the pertinent question becomes; how do I install said driver?

I am reasonably computer savy, but have little experience with the ubuntu line of things. So I have no idea how to install the driver. Anyone that can help me or point me in the right direction?
