I admit it's a bit of bragging, but I'm really glad I constructed it. I pulled out the foam padded case with everything in it from the closet, took everything out and placed it on the floor to connect the DTV to my new LCD TV. Turned the box on, and the picture was flickering badly. Woops, have to trim those signal levels. Opened the box, and trimmed the potentiometers for Csync mix level, luma level, and chroma level. Voila! Crystal clear and flicker free picture. Yaaay! s-video dac/mixer/driver circuitA part of a picture I just took of one of the credits screens The checkered pattern in the blue is some digital enhancement effect from the TV. I didn't bother to sort that out.

So you are saying you took this picture with a camera instead of a video capture card?

Yes, that is correct. The only video capture card I have is a 4 channel video surveillance card (deep in a closet somewhere), and it only accepts composite video. I haven't found a decent capture card (equal or better than yours) around here yet that doesn't cost a fortune. So for now the solution is TV + camera.

Wow, what a neat soldering job with the circuit! Very much worth bragging, I'd say!

Just search ebay for video capture cards. Old PCI versions (like I have) usually cost about US $10 or less. (as for GBP, I have no idea) Just try to get one with a conexant 878 or a BT848 chip. I have a spare laying around I'd be happy to give you, but it is only NTSC.

I found one card on ebay, but it probably is NTSC. However, I actually found a Hauppauge Impact Video Capture Board on a national auction site, and this card has a Conexant 878A chip. It handles both NTSC and PAL, so I'm fully covered. Reasonable price too. Hopefully nobody (but me) places any bids. The seller lives along my way to work, so no postage fee either. Almost too good to be true...
But you have to admint it was a darn good "grab" via my TV. ;D
[Edit] I snipered it. 18 bucks. It's going for $100 in the stores. Nothing is cheap here... And if buying something from outside europe, there's a big chance of having swedish tax and toll fees added to it. That doubles the price for small purchases, so there's usually no idea in the first place.
