I'm testing the videoblaster now. 

It can't save MPEG or JPEG-files. Only GIF, TGA, BMP, PCX and
some other formats.

It can freeze a picture for digitizing. I can't test how fast the
digitizing is during lack of memory (i must save pictures on floppy).

I haven't tested all possible resolutions yet. But the software supports
resolutions up to 1000 pixels I think. 

You can use the most VGA-cards. But it must have a feature-connector. 
A VESA-compatible Super-VGA card is recommended. 

Yes, you can watch TV in Windows if you want it. 


The Videoblaster seems not work with OS/2 2.0 GA under WINOS2. DOS 5.0
and Windows 3.0 works fine.

The videoblaster can't be used in a machine with 8514/A-adapter. I
don't know if S3-cards work, but all VGA-compatible cards with a 
free feature-connector should work. 


I'm not sure if I want to recommend the Videoblaster because it don't
work with OS/2 and 8514/A. I'm also using the Screen Machine fram card
and it works well with OS/2 in winos2 running winos2 in VGA-mode. 

If you only uses Windows, the Videoblaster is a cheap choise. The 
picture-quality seems enough good for most usage. The windows-software
are somewhat better than screen machines, but has no picture archiving 
feature.

The prices in sweden is for Videoblaster: DM 700 + taxes, for
Screen Machine: DM 3000  taxes.

Hmm, studio quality digital PAL video is just 768x576 in screen size,
so 1000 pixels is just not possible with such a low cost product !

Please can you look into the manual ?

Is the pic YUV coded or RGB digitized ?

Does it also support 38 Khz and up to 50 or 64 Khz horizontal scanning
frequencies from the SVGA card ?

How do you connect it ? 
Does the SVGA output go via the feature connector to the Video Blaster
?
And then do you connect your SVGA monitor to the video blaster card ?

Does it also work under win3.1 in a 800x600x256 windows screen size ?
(with 70 Hz image frequency (49 Khz horizontal scanning frequency)

Does it also work with 1024x768x256 win3.1 screen size ?

>Yes, you can watch TV in Windows if you want it. 

What resolution has the TV-window (x-y-screen size)?

I hope to get more info on it.

The software seems capable to make pictures larger than 768 pixels by resampling. I.e, the
resulting picturefile can be larger than the video source. 

But it seems the Videoblaster also can be configured to accept some other 
video sources with wider bandwidth but I can't test it because I don't have
any composite video source with other bandwidths than PAL and NTSC.

RGB I think.

I haven`t tested it yet. The manual says nothing.

The VGA-card connects to the videoblaster both with a cable from the 
VGA-output and the feature cable into the videoblaster. The monitor connects
directly to the videoblaster.

The Readme-file on the diskette says videoblaster only supports 640*480, 
but support for 800*600 also delivered, but it's not tested on all 
VGA-cards.

It's selectable from a very little box (bad quality) to the whole screen by pixels.
