For an AverMedia AverTV DVB-T card, 2.6.0 or 2.6.2 support it out of the box. I have only just got V4R2 downloaded, so as soon as I have upgraded the kernel on my test box I will tell you how MythTV copes with DVB drivers.

Sorry, I should have added something here earlier. I got it to work. Look in the KnoppMyth->General forum

Some further information that may save someone some time:

1) This card does not seem to work in a Compaq Deskpro SFF EF. bttv reports IRQ lockups, despite my best attempts at turning all devices off in the BIOS, et c.

2) I think that this card fails to tune when using bttv 0.9.15, which means that KnoppMyth V4R4 is unusable, but V4R3 is OK. It also means that any kernel newer than 2.6.5 is unusable. Note that I tried to downgrade the version of bttv in V4R4, but after insmod ./bttv.o with my newly build old bttv, dmesg showed that it reloaded 0.9.15

This took me over 100 hours of installing, debugging, reinstalling, pulling hair out, swapping computers, and cursing to discover this

So I'm not going mad then...

Thank god for that...

Damn. I had to go and delete V4R3, didn't I.

Note that I have still not got this card working reliably with MythTV. The tuner on this card seems to be very unreliable. MythTV's advanced setup says 100% signal strength and 50-60% signal to noise. The mythbackend reveals several hundred stream errors a second, and the most I have been able to record is 15 minutes (before the backend silently crashed).

Looks like the problem I was having on V4R4, which I thought was caused by bttv-0.9.15, is a motherboard-dependant thing.

I can not seem to get my avertv dvb-t card to work under knoppmyth, it is fine in windoze and the brooktree chip is being seen on boot up. Do I need to add any modules if so how

KnoppMyth doesn't include the DVB drivers so MythTV isn't compiled w/ DVB support. I don't have one of these cards...Being in the US, DVB isn't really any option because each provider scambles the signal in there own way(as I understand it, anyone know for sure?). What all does DVB need? Just the drivers from LinuxTV.org and MythTV compiled w/ it? Let me know and I'll include it in R5. cesman

In reply to Chris' original question, bttv (Video4Linux) does find the BT878 chip on the Aver card, but that is not all that is required to drive it. There are three parts to DVB support: Having the dvb-core installed (either in the kernel, or as a module), Having appropriate dvb-drivers installed for your card, and Having Myth support for DVB. Now, the first two I know well. For an AverMedia AverTV DVB-T card, 2.6.0 or 2.6.2 support it out of the box. I have only just got V4R2 downloaded, so as soon as I have upgraded the kernel on my test box I will tell you how MythTV copes with DVB drivers.

I would be very interested to know how you went with this. I'm contemplating the purchase of the DVB card you mentioned, and would like to have a better idea of how much trouble I will have setting it up. Given my mediocre knowledge of Linux (enough to set it up, run it, and do most things from the command line, especially if I have some form of help available) it's not a project I feel confident to take on myself.

Since I'm a lazy SOB, I'm trying the automatic upgrade of the kernel... will post back when it completes since you weren't 100% sure whether the automatic upgrade would work.

I had to go and delete V4R3, didn't I. I did get it going after a fashion with the 2.4 series kernel, but it wasn't stable and I was getting the IRQ lockups you referred to. What a pain. My machine is a fairly standard "whitebox" PC. I was getting to the stage where I suspected the machine was pretty much screwed. The good thing is that I've learnt one hell of a lot about compiling kernels - something I've never done before...

Looks like the problem I was having on V4R4, which I thought was caused by bttv-0.9.15, is a motherboard-dependant thing. I built a new computer (Gigabyte K7 Triton GA-7VM400AM with an AMD Athlon XP) and it reads data from the AverTV DVB-T card just fine. So, to recap: Compaq DeskPro SFF EF, PII350, would not work with any version of KnoppMyth, or any 2.6 kernel. VIA EPIA M10000 would not work with V4R4 (bttv-0.9.15), but would work with V4R3 (bttv-0.9.12) or 2.6.5 (bttv-0.9.14?). Gigabyte K7, Athlon XP 2200, works fine with V4R4, and probably 2.6.5 Note that I have still not got this card working reliably with MythTV. The tuner on this card seems to be very unreliable. MythTV's advanced setup says 100% signal strength and 50-60% signal to noise. The mythbackend reveals several hundred stream errors a second, and the most I have been able to record is 15 minutes (before the backend silently crashed).

You are not exactly inspiring confidence in my purchase of said DVB card... Oh well, by the time I've finished finding cards that work properly now I'll have a great collection of cards in the future when they're all supported... In the mean time, I'll keep experimenting and learning...

I was having some success on an old Gigabyte motherboard which suddenly decided it had had enough and died on me recently. After the recent purchase of a Qbic barebones system (P4/845 chipset) I'm back to square one with it - crashes, IRQ lockups, repeated tuning failures etc etc. My old Leadtek analogue card is now working beautifully in that machine (though it's a cast iron pain in the bum changing cards in the damn machine) Definately time to go for another capture card... I may well look at a USB solution this time since the Qbic only has the one PCI slot. Damned if it doesn't look a whole lot better than my old midi-tower sitting in the TV unit though, even if my father does bitch about the excessivlely bright blue power light on the thing...
