I've got some serious problems with my capturing.

I'm using the AverMedia Game Broadcaster HD and a Aten VS-132 videosplitter.
The system I have my Avermedia card installed in, has Windows 7. The system I'm trying to record has Windows 98se.

In DOS;

In Windows 98se;

Both the Avermedia software and VLC have these problems.

So my questions;

- Why is DOS displayed in such a small part of the screen? Why is it not stretched out? And why do I see the Win98se desktop in the top half? I didn't boot into Windows and then ran the game, I booted into DOS. This is not how I see it on the screen that's hooked up to the system. This is only in Aver Mediacenter 3D and VLC.

I should note, that the boot-up screen with the memory count, cpu-info and the looking up of the hdd/cd-rom drives, is displayed properly and fully stretched.

- Why is the Windows input garbled/distorted like that? Again, on the monitor of my retro-system everything is fine. But the recording software messes it up.

I hooked up the retro-system directly to the Avermedia card and I got this in Windows;

As you can see, it's not centered correctly. Again, this is what I see in both Aver Mediacenter 3D and VLC.

Also, when I record in Avermedia, I get an on-screen display that tells me the resolution is 720x576. But I put it at 800x600 in the settings.
When I check the codec information while watching the stream in VLC, I get this;

1600x1200?

Another strange thing is, I've had it working right but I have no idea why it's not anymore.

Can you guys help me out here? I'm getting very frustrated.

In DOS: You need to set capture resolution to 640x480, or else the screen will be captured in your current settings of 1600:1200 and DOS is only stretched 640x400 from screendoubling. DOS picture is not streched out in VGA mode in any resolution except native 320x240 and 640x480 and above on the Avermedia. DVI capture for DOS does not have this problem (which is why me and Mau1wurf1977 prefer DVI capture whenever possible, though with old 3D accelerators VGA is your only option)

Windows: Be sure to set 60hz in Windows98

In Aver MediaCenter 3D; Settings > Capture > Configure Input Source > Configure Recording > H.264 Edit > setting the video size doesn't seem to do anything for recording in DOS.

As for Windows, The S3 drivers I installed were to blame. Trying to solve that now.

Yea with 640 x 480 and higher, I never had issues capturing 60 Hz signals.

For 320 x 200 games under DOS I run something with 640 x 480 first, hit record, and then the capture works. You will still need to crop and resize the video.

For newer machines go with DVI > HDMI. Works beautifully.

Here some captures:

This is not going well. The S3 drivers were not to blame. When I select a resolution above 640x480, that's when the stream gets borked. At 640x480 there's not distortion/flickering/borked screen but it's all red-ish and shifted a bit to the left. Might be the pci slot though.

MediaCenter can't edit that setting required for DOS VGA capture. You need to use RECentral (newest Avermedia software) or VLC.

In VLC:
1. Open Capture Device
2. Then select DirectShow, Avermedia HD Capture and the sound device that has the sound input.
3. Click Advanced Options and check Device Properties, click OK.
4. Click Play
5. Click OK on the first window that pops up.
6. On the next one select 60FPS as framerate and then 640x480 resolution. (select higher if you intend to capture in higher resolutions)
7. Click OK on all the next windows.

I still think it's a driver issue as my guess is that any DOS game that runs in 640x480 or 800x600 will look fine.

Try another card if everything fails. My personal favorite is a Voodoo3 PCI for VGA capture. It has very good signal quality, it is fast, and it centers the image on all resolutions I've tried. Using a S3 Virge is asking for trouble with the Avermedia (and bad capture quality if you have a lowend card)

I picked the S3 because it's a 2D card. I'm worried that a 2D/3D card might interfere with the results or do the accelerating instead of the 3D card I want to record. Are my worries unfounded?

Yes 😀

I normally run 3DBlaster PCI (Rendition Speedy3D, Rredline, CGL, Direct3D), PowerVR (PowerSGL, Direct3D), Voodoo1/2 (Glide, Direct3D) in my bench system and have full control 😀

A Voodoo3 can only accelerate Glide, OpenGL (via miniGL ICD) and Direct3D. With Direct3D you can control that with the 3DCC tool. OpenGL by using the OpenGL drivers/wrappers/ICD in the game settings. For Glide it's a bit more tricky with a Voodoo3 and you want to run on a Voodoo1 card, a suggestion swapping out the Voodoo to a Nvidia card (Riva128, TNT, TNT2, etc) as that only accelerates direct3d and OpenGL.

If you insist on using a pure 2D card, then go for the ET6000 😀

I know I'm late to this thread, but I'd like to give you a commendation for this solution. I just got a Game Broadcaster HD in the mail last night and have been having an "OUT OF RANGE" issue when capturing DOS-style output. Switching the resolution in Windows 95 to 640x480 allowed text video to stream through the device after shutting down Windows 95. It's still confusing to me how that did the trick, but it worked!

I have shifted image on aver c127, under windows 98se and using something like TNT2 I can shift image manually by PowerStrip, but when Glide activates it still shifted right at 6-8 pixels.

In glide mode I tried to play with SSTV2_BACKPORCH variable, but still nothing ((

well, I found a solution.
it is two variables for v1 and v2
SST_BACKPORCH
SSTV2_BACKPORCH

2017-01-26_08-59-13-png.120753

and in bat file it will be something like that
SET SSTV2_BACKPORCH=0x1D001D

and tada!

20170126093207-png.120754

3dfx.bat for Blood 1, Glide, Voodoo2, avermedia c127:
SET SSTV2_BACKPORCH=0x1D001D
SET BUILD_640x480=1
SET BUILD_CONVTEXTURES=1
SET BUILD_GAMMA=1
SET BUILD_RESAMPLE=1
