No color from VHS on DVD/VHS player

There may be an input selection between Composite and S-Video that needs to be toggled in your Hauppauge software.

Your Hauppauge card may also be in the wrong signal format mode (NTSC or PAL). Your source device and your Hauppauge card need to be in the same mode (both NTSC or both PAL) for the capture to work properly.

If your NV-VP33 is a SCART output, then you may need to check your SCART adapter and your device as not all devices output both S-Video (Y/C - two signals) and Composite (CVBS - one signal) type signals.

If your SCART adapter has both Composite and S-Video outputs, try the other one.

And finally... if you're playing an NTSC tape/DVD in a PAL player, it doesn't mean the output is true NTSC 3.58. Most times it's NTSC 4.43 which is OK for TVs, but NOT okay for video capture devices. Video capture devices need true NTSC 3.58 to sync the color carrier properly.
