Future of the Linux-Driver

Thanks a lot Mike.

I think my problem should be my Ubuntu is amd64 because header of v4l2-compat-ioctl32.c is about 32bit and 64bit conversion.
Tomorrow I will reinstall my OS with Ubuntu x86 (32bit)

I had this issue too (Kubuntu 64-bit) - I've replaced the v4l2-compat-ioctl32.c with this one that I found with google.
It seems as though this file is a fairly standard file and isn't specifically modified for the TBS card.
http://lxr.free-electrons.com/source/drivers/media/video/v4l2-compat-ioctl32.c
The make has just completed, so I'm about to install and reboot .. My fingers are crossed.

Well - after the above, it Makes, boots and loads.. now to see if I can make it work with MythTV...

Thank you very much.
I will try to build with your suggestion on Ubuntu 11.04 amd64 first.

[stevellion]

OK - No "Error" messages, but not finding any channels.
This is my first time with DVB, so could be doing something wrong.
It's the same problem shown earlier on page 1, but solved by a IOMMU flag relating to XEN. I'm just running Kubuntu Natty AMD-64 with my updated v4l2-compat-ioctl file

So - any suggestions on the messages below?

Still no luck - and no real ideas now... Anyone have any suggestions?

I'm considering reloading the machine with 32-bit.. but would prefer to keep it at 64-bit really..

Ideally, of course, TBS should be releasing an updated kernel driver against the current version of Ubuntu...

[stevellion]

Hmm.. messing with frequencies,, some scanning works.. Just I don't really understand how to use Scan-s2.. but it's found channels.. Maybe I don't need to reload .. will update.

[stevellion]

OK, I have Lock... szap-s2 works.. - Kubuntu Natty AMD64

Problem is, I don't really understand the channels/frequencies/tuning, or how to watch the channel it's locked on to (just for testing) or then, how to configure MythTV to work with these cards.
Here's the lock output - some help would be great. - Please help with the next step for a newbie...

PS - Just to confirm my procedure.

1) Download/untar the driver files from TBS
2) Apply the patch
3) Overwrite the v4l2-compat-ioctl.c - only needed in linux/drivers/media/video with the one in my previous post (just the current one for 2.6.38 I think)
4) Make and install.
5) Mess about with some black-art stuff about frequencies etc.???

OK - Next bit - HELP please!
I've got this output from MythTV as I try to scan from there - something about DiSEQ setting.

Snapshot of MythTV output as it tries to Scan.

All I know is that I've unplugged my Sky+ box and plugged in the TBS card instead. I believe I have a quad LNB... (but just 2 cables coming in to the house)
Logically I don't have rotors etc, but not sure what switches if anything I need.

Scan and Szap still works - no changes since last night.

[stevellion]

More progress.. I set an LNB in MythTV - just a Europe Universal with pre-set settings.. MythTV is scanning now, finding plenty of channels. Woo-hoo.
