I found some old reghacks that I *think* do this, but I don't have an RRS up and running at the moment to test it.

If memory serves you run the reghack before setting up AVI_IO or VirtualDUB for the capture. Start PC-VCR and I think it reverts back to MJPeg.

Wanna be the guinea pig? ;-)

Hi Doc,

Count me in!

Although I did e mail FD with the appropriate dll a long time ago, but Arthur didn't think it could be hacked in the "Marvel" way.


Let me know what to do and I'll have a go tonight!

A question Doc...

I might go to a G450eTV if all else fails. I'm led to believe that you can use AVI_IO to capture full res with the G450eTV with < 933 processor.. Can you give it a whirl and report back. I've just upgraded to an 850 (the most my board can take at the moment).

I'm making a big assumption here, but as I'll be using AVI_IO for capture only and not for any "timeshifting" would the capture requiremnets be < 933?


Thanks as ever,


Nick.

With eTV and AVI_IO the only capture modes are RGB, YUY2 and whatever compressor you want to use. No MPEG-2 from AVI_IO.

The PC-VCR program is limited to RGB and MPEG-2 only and enforecs a CPU restriction on full frame captures. I think it's somewhere between 933 and 1ghz.

That said VideoStudio5 does NOT suffer this CPU restriction. Now...this "experiment" I did is not anything Matrox would support, OK?

That said I did a 0 drop 704x480 MPEG-2 SP capture with the eTV in a PIII/850 system using VideoStudio5: Asus P2B, 128 megs, Santa Cruz audio, 40g Maxtor ATA100.

Not much difference, but there 'ya go. Given the prices of 1ghz CPU's these days...

I'll email you guys the reghacks.....

Hi Doc,

Thanks for the Reg Hack.

You may have to help me a bit here…

I’ve imported the hack into the registry (having made a back up first), I guess I’m expecting to see something in AVI_IO Format box that leads me to YUV, but I don’t.

Can your memory help me here?


Secondly, I assumed from Haig’s response in http://forum.matrox.com/mgaforum/For...ML/003019.html that AVI_IO would capture mpeg2, I guess it doesn’t, but as VS5 does… can I assume (yet another assumption) that when Markus gives us the Direct Show version of AVI_IO that the mpeg2 defaults will be seen by AVI_IO?


Regards,

Nick.

[Dr Mordrid]

The reghacks were just for the Rainbow Runner Studio + Mystique combo.

It's VideoStudio that doesn't use the hard-codec CPU limitation on MPEG-2 captures and allows you to capture with a slower CPU. AVI_IO just sees RGB and YUY2.

As to what AVI_IO will do with DirectShow + eTV....we'll have to wait and see. I'm not assuming anything.

Hi Doc,


It's the Mystique220/RRS that I've got...

Don't see any YUV options in AVI_IO once the reghack has been applied.

Thanks, anyway.


Another assumption here(!?)...

Can ordinary captures be full res with < 933 using PC-VCR and eTV?
Is it only the "timeshifting" feature that stops you?


Regards,

Nick.

[Dr Mordrid]

PC-VCR locks out full frame MPEG-2 with processors below 933 mhz. VideoStudio does not, so try capturing full frame with it instead.

Hi Doc,
Could you please send me the reghack for the RRS?

Although I have a Mil II/RRS i will give it a try tonight if i have it.

Thanks

Understand that I'm not sure if this works at all, or what driver version it might work with if at all....

That said it's on the way...

Hi, Doc,

Would you please also send me the reghack?

Thanks.

First post in this thread was:

<font face="Verdana, Arial, Helvetica" size="2">Can i in any way capture YUY2 with the old rrs on Mystic</font>

So, what's the answer guys?

[Nick Piercey]

Hi Patrick,

I applied the hack, rebooted, started AVI_IO and selected format, but there was nothing to suggest which was the YUV setting.

In the RGB box no frame size was listed, so I even tried capturing at this "setting", but my PC just rebooted itself!

I'm still none the wiser.


I'll wait for T_I's review of the eTV and may go down that route.


Regards,

Nick.

PS If anyone else has had success, please post away!

[Patrick]

Thanks Nick. That's not the answer I wanted to hear, but I appreciate your response nonetheless.

Hi Nick. Working on it (slowly). Plenty to be done yet, but I haven't experienced the problems that others are reporting with screen corruptions or lack of quality with the eTV tuner, despite it being installed on a VIA chipped mobo. Or, as I've pointed out many times in the past, peoples perceptions and expectations vary (witness the fact that I'm perpetually amused when people report that they're dropping one frame a minute or whatever). Anyway, plenty of work still to do, keep your eyes on the main site's news page frequently (all of you <grrrr>)
