Re: Hauppauge ImpactVCB-e 01381 PCIe driver resolution.

[Steve Cookson <it@sca-uk.com>]

Hi Devin,

Thanks for responding.

So my question would be then, is it worth fixing?

I can't find any PCIe cards that give me a reasonable quality.

If I use an external card like the Dazzle it seems quite fast and better 
quality than many s-video cards.

Could the ImpactVCB-e be better than the Dazzle?

Regards

Steve.

ImpactVCB-e 01381 PCIe card working on Linux (I'm using Kubuntu 13.04) 
with greater than 320x240 resolution.

of work on the driver last year to fix a variety of bugs, but didn't get 
around to making the scaler work properly.  Most likely the card only 
works right at it's max resolution (720x480 for NTSC or 720x576 for PAL).
