The TV cards will always be very slow on RadeonHD machines because there's no way of directly displaying a YUV422 format bitmap (like overlay does). At least until there is a way. :) I can actually do it with RGB565 but that sucks up a lot of PCI bus bandwidth.

Do you know the reason why that is?

Yes. The driver is still a work-in-progress.

...and probably a solution to be able to use YUV at last?

It's on the to-do list.

@thread

now that there is experimental NTSC support, i'd like to try this on my SAM -- if for no other reason than i miss my gamecube and we have no television to hook it up to.

can anyone here actually recommend a specific card that they know works before i start buying kit off of amazon?

All the Win/TV cards I've tried have worked so far. In fact I only have one TV card that doesn't work, and that's because it uses a PCI bridge which AmigaOS 4 doesn't seem to cross - it just doesn't see anything past the bridge (including the Conexant chipset). I think I've tried about 5 Win/TV cards so far - I use them as my reference platforms.
I've also heard that the ATI All-In-Wonder cards (I think it was) worked too, but I think they'll be 5V so no good in a Sam. It's the 3.3V specification you need to be careful of.

Check in Ranger if the bridge's IO and Mem spaces are enabled (the "Command" field). UBoot doesn't enable the bridges properly; at least on the A1-XE.

Back when I first started tinkering with Radeon HD cards (actually, it was a Radeon X1300), it took me a while to figure out why the card wasn't responding. Once I discovered that it was the bridge's fault, I added code to the RadeonHD driver to check for any bridges between the graphics chipset and the CPU, and reconfigure them if necessary.

It seems like it's initialised ok, it just can't see past it....

I can see the problem now; you're using a Pegasos II. The Pegasos II's firmware doesn't scan for PCI devices behind a bridge. This is why Radeon HD cards don't work on Pegasos II machines, and the problem will probably never be fixed.

WinTV-HVR-1100-L.P. Hauppauge Low Profile PCI DVB-T Digit

Got this to display output from a DV camera connected to the S Video socket.
Very good picture but black and white only.

So far failed to get a freeview box to output to the same socket, but got more things I can try yet.

I already replied to this on AW.net, but for the record - if you press 'S' with the display window selected, it goes to S-Video mode and you get colour with an S-Video signal.

Yeah, but somebody looking on this thread might not have seen - best to answer it in both places. :)

Yeah, totally get that.

I dont think the scart adapter I was using was bi directional.
I have ordered one that is.
I will publish the results on both sites, once tested.

Cheers.

Is it possible to get the capture of the Happauge PVR cards working?

I can't, I'm afraid.I need the datasheet for the MPEG encoder chip, and I can't find one.Sorry!
If you can find a full datasheet for the Conexant Cx23416 let me know!

That would help, yes :)
We still need the datasheet for the Conexant Cx22702 though I'm afraid. I may mess around with the 23416 a bit though, in case anyone needs a video encoding from composite video :)

I would get in touch with Frank Mariak if I were you. He had some capture working with certain boards back in the morphos 1.3 days iirc. He might have docs or code to help.

Any change to get dvb-t working? I do realize that it is quite different task than analogic, but in many coyntries all tvs are dvb
