The Hauppauge HD PVR should work with any device that has component outs. I've used it with the Motorola 3416 and also the Shaw Gateway.
I'm being a bit cautious, because I've been able to capture HD through FireWire to my MacBook Pro from my DCT6412 III, but not from my DCX3400-M. It gives me M2T files. I can only record non copy-protected programs, but I believe that component recording would allow me to archive anything in HD. (I do my archiving by playing back material I've already recorded on the Motorola PVR.)
Since I do not need to capture live telecasts or change channels, I figure some of the complaints some people have with the Hauppauge would not apply to me. I would have to use the third party software for the Mac, though.
I do not have to hurry, because I can use my present set-up until my DCT6412 packs it in. I haven't figured out if the new Hauppauge HD PVR2 machine would have any relevant advantages over the current model. It doesn't seem to be available in any stores yet, even in the U.S.
Some time ago, I tried an EyeTV HD box, but connected via component to my iMac at the time, I got a stuttering picture. I returned it right away. I noticed recently that my local BestBuy store had several of those on the shelf, marked as "open box", leaving me thinking that its common for people to return them.
Thanks for your previous response.
