I don't think there are any "can" tuner solutions that do both pal/secam and ntsc, and for any digital TV you pretty much have to turn to silicon tuners I think. I also think that is where you can find solutions that can do both traditional pal/secam and ntsc and maybe also both dvb-* and *tsc. Video decoder-wise there are many solutions that can do all three standards. Microtune and others make chips for several of these and QAM-geared and even for mechanical systems purposes (factory/lab/servo equipment) but no everything-in-one AFAIK. It's possible that everything-in-one just can't be done technically or economically, but the fact that they can be designed/manufactured almost equivalent and still have such a broad area of application clearly show their merit. Not to mention that they're already being used all over the place in, well, TVs for example. Other chipmakers are xceive, fujitsu, TI (they also make a prominent video decoder chip TVP for which there are extensive datasheets on the net), probably also philips/LG, ... [google] ( AFAIU it's a double (serial) PLL system so that the dividers/multipliers can effectively both be set rather than merely a few fixed combinations -- anybody more "skilled in the art" as the patent language goes, feel free to comment ) I'm only relaying from my own research and I have no ties anywhere in this industry, but I think you're going to need to have a significant budget and talk to -- for example -- TI and fujitsu if you want some universal card/USB stick to be put together. You'd also need drivers :) Hauppauge's stuff (or elgato) might be already extensive enough for the multi support you want. But there too, you'd also need drivers :) HTH, Dan
