I have an ATI Radeon All-In-Wonder 7000, no, I'm not silly enough to try and use the AIW portion of it. What I am considering however is that I have this ATI to Component Out cable for the TV Out. Will this work with KnoppMyth R4V5 out of the box, our would it become more of a headache then it's worth?

Pretty sure you'll have to check out the "tv_output" tagged branch of the GATOS cvs ati.2 driver and recompile it against a fresh X11 install. You may have to recompile X as well, as the Adventurous Setup suggests.

This is on my list of things to do; I'll post feedback here when I get around to it.

Thanks Mark, that's very helpful. And since I'm feeling adventurous I think that I will give this a go tonight if I have time or tomorrow evening if all else fails.

PS - If you were trying to compile X 4.3.0 from source as I was, you'll run into compilation issues with a 2.6 kernel. There's an extraordinarily helpful thread here with some fixes for a few files in the tarball.

I ran into a slight snag... it seems that I gave my AIW 9000 away a number of months ago because a friend wanted to watch TV on his computer.

Let me know if it starts looking worthwhile and I'll figure out a way to nicely demand my card back.

Well, it took me some time to get X11 to compile correctly, but since the drivers available seem to be built against (at the latest) 4.3.0, had to go with that. No biggie, the patches I linked to worked fine.

drm-kernel, however, did not. It did not compile whatsoever, and perusing the Makefiles and source seems to indicate it was never designed to work with the 2.6 kernel. Sucks.

Still got tv_output to work, and the theatre module loads at startup. Unfortunately, DRI gets disabled, and though I'm at work (and unable to verify this) I imagine this means the framerates will suck.

I'll keep working on this and post back when I'm able to test things out, but setting up tv_output was straightforward and basically worked with the instructions here (xmkmf, make, make install) against the X11 tree I'd compiled earlier. Not sure if it's actually outputting anything, but I'll give more feedback when I get a chance to test it. Looks promising. Might have to ask the developers for some help getting drm-kernel to build, but it may not even be necessary (since I'm not capturing video).

Anyway, more later.

we are on a KnoppMyth forum, and KoppMyth has not ever shipped a release with a 2.6 kernel, so anyone who has not upgraded their kernel may not run into this problem. At least until R5 comes out.

Fair enough. I'm a "latest and greatest" kind of guy, and I like that 2.6 comes with a preemptible kernel and ALSA built in. Of course you can get that with 2.4 kernels, but I appreciate you guys trying to make this a bit easier for the average PC user who doesn't want to get down and dirty with this kind of stuff. I just think it sucks that a lot of the development being done for the components myth relies on has been mostly 2.6-based. I'm no kernel hacker and I'm definitely not a driver author, so this is a situation I've been forced to deal with more than anything. But this is more of an aside than anything else, I'm not trying to step on anyone's toes.

I've read before here that "no one" has gotten a Radeon 9000 AIW to work with Myth. Sounds about right for capturing, since the ivytv folks say they're not getting a full set of v4l hooks and such. But tv-out is possible at least in theory, and I wanted to give it a go. And for anyone else trying, it'd be nice to have all of the resources in one place.

well you do realize that the kernel in knoppmyth has been patched with preempt and ostreaming, so those are not real issues, however there are several new drivers for 2.6, but I guess those will just have to wait for R5 it will have a 2.6 kernel. My guess would be 2.6.9 baring any major problems when it comes out. I say 2.6.9 because 2.6.8 does have some serious problems, particularly with ide cdrw drives. I guess that's what you get when they are still doing development on the "stable" kernel. I guess we'll have to live with those kind of issues for a while now until Linus decides he want's to go ahead and start the next "development" kernel.

Huzzah! -- this is working beautifully. TV Out took me some time (X11 compilation issues, mostly) but the gatos drivers compiled nicely and, though I am not up and running with the DRI module yet, I can confirm that the Radeon 9000 AIW is fully capable of TV Out w/ Myth.

It looks beautiful on the set. The drivers will do TV mirroring only (no Xinerama yet) and even then, only when the resolution is 800x600 @ 60Hz. This kinda sucks because my flat panel can only be driven at 1024, 832, or 640, otherwise there are strange elongation effects on the screen. Regardless it is in fact working quite well via S-Video and Composite-out.

The procedure went something like this:
- Download X11 source (I used 4.3.0)
- Whine about incompatibilities with 2.6 kernel, fix a few source files (links above)
- Compile X11
- Download gatos drivers, CVS tag tv_output
- Compile against X11 tree and install
- Change settings in /etc/X11/XF86Config-4 to use the TVOutput option and appropriate standard
- Restart X, et voila.

I'll be working on gatos DRM over the weekend, but things look very good. And unless you have a 2.6 kernel, this should be a very straightforward (and successful) process.

Yippee!

That's great news. After digging around in one of my many drawers ladden with old computer kit I discovered that at some point over the past several months I got my ATI AIW 9000 back, and since my mother board is now beeping and not displaying video with the Geforce FX5700LE installed, I'm about to put the ATI in my MythTV box.

I just swapped out all of my SATA gear for PATA, so I'm going to give it a go with KnoppMyth keeping SuSE 9.1 PRO as a fall back option.

I did all these steps and I was also able to get TV-out working on my 9200SE. My only problem is that xv did not seem to install with the drivers. This causes full screen video (MythTV, mplayer, xine) to lag and lose frames since it does not have hardware overlay support.

sootzoo, were you successful in getting xv installed when you got the tv-out working?

I should point out that, with R4V5 you do have to deal with the XFree86 build problems as highlighted in the above posts. If you don't have sedit, you'll have to decipher the sedit commands to make the changes to the proper files.
