I am contemplating buying a 42-43" rp tv. I've seen some deals on mitsubishi and hitachi sets. My question is how important is the new dvi-hdcp standard? My understanding is that a lot of the new models coming out this summer will have it, so it does appear to be becoming the defacto standard. Is it possible to manufacture adapters for sets that don't have it so that in the future you can get hd movies at full resolution? It seems a shame to not be able to view hd with full resolution if that comes to pass. I've been reading the threads, but I haven't seen anyone address the issue of whether adapters might be possible (or likely) Unfortunately, for the near future it would appear that the deals will only be on the sets without this standard, so in order to get the dvi-hdcp it means paying more. thanks for input.

P.S. I wanted to mention that I've seen some people say "no big deal,you can always use the component video inputs" implying no loss of definition and others say "you'll be out of luck". Its confusing.

Lawrence, The DVI/ HDCP/ HDMI standards will in fact be that; standards. I'm sure you know that this is an all digital transfer method were as component is digital, from, let's say a DVD, then a small down conversion to analog through the cables and then back up to digital for your HD set. This is not a huge performance hit, but your not seeing the best picture possible and is just that a performance hit. In terms of there being an adaptor I'm not really sure because, to me, it wouldn't benefit anything at all. Most TV's that come with the DVI interface have component video with them and TV's that don't have DVI wouldn't benefit from a source component with DVI being routed to an inferior cable. The TV isn't the big deal. It's the recievers and all the other source compponents that are going to need DVI/ HDCP/ HDMI switching now. This is the real problem. Component switching just became a standard on larger recievers a few year back and now they have to switch to the DVI standard. Hopefully once HD-DVD is debuted it will come standard with DVI/ HDMI interface on it and this will prompt reciever makers to do their thing as well. Honestly, paying more for the DVI feature shouldn't be a huge deal. It depends on what types of sets your looking for. I've seen low end JVC TV's with DVI on them for less then 1700.00. Honestly you shouldn't be paying more then one hundred dollars for the DVI diffrence in most TV's, unless it's just a huge diffrence in the quality of the manufacturer. (I.E. KLH to Pioneer Elite) When you go to buy a TV and if you do get one with DVI make sure it does have the HDCP (High Definition Copyright Protection) standard with it. If not, virtually no device with a DVI interface will function with it in the future. Also, if you luck out, you will be able to get one with the new High Definition Multimedia Interface or HDMI which looks exactly like a DVI connection, except it does Audio and Video through it with a huge bandwidth increase. This plug is available on the new Samsung DLP TV's already out and this is what will be the new standard. Well I hope this got you some of the information you needed. let me know if you have any more questions.

Since HD-DVD will output only on HDMI (which DVI-HDCP is compatible with except for control data and audio) I have to disagree with you Paul. The whole point of HDMI/DVI-HDCP is that they are encrypted connections which prevent recording. If HD-DVD was going to be output on component video Hollywood would not have forced the encrypted connections so quickly on consumer sets. Lawrence if you are going to buy a HDTV I recommend one with a HDMI/DVI-HDCP connection. Though many think that pre-recorded HD-DVD should output on component video it will not happen! Neither the government nor angry consumers will stop Hollywood from making HDMI the only output for video on pre-recorded HD-DVD. It may not be right for the consumers who have spent thousands on a HDTV without a HDMI/DVI-HDCP input, but Hollywood is the owner of the content and therefore can do it. As for adapters for HDMI/DVI-HDCP under the DMCA(Digital Millennium Copyright Act) anyone that sells or even buys a device that converts HDMI/DVI-HDCP to component video can face serious legal penalties. That may not stop such devices from being sold but they would be both expensive and hard to get because of that. If your trying to get a HDTV on a cheap then your best bet is waiting for this years models to come and buy one of last years models when the stores are clearing inventory(easiest method). Since most of last years HDTV models from the major manufacturers have DVI-HDCP it shouldn't be hard to find one of them on sale. Mitsubishi is the only major TV manufacturer that still doesn't have DVI-HDCP on it's HDTV's. An example of how worried Hollywood is over illegal copying of content is that future DVD players that can scale video to 720p/1080i can only output on a DVI-HDCP connection! If that's any indication of Hollywoods paranoia then can you imagine them outputting pre-recorded HDTV over a component connection that doesn't have any encryption?

That's all very true. If HD-DVD players didn't have copyright protection everyone and their brother would have a High Def master of their favorite movies for distribution to every Tom, Dick and Harry across the globe. Also I meant, He shouldn't get bent out of shape about paying more for the DVI because of all that nifty stuff stated above.

you're confused because others are confused we can predict, but nobody knows for sure what will happen. personally, i'll prepare for the worst-case scenario that if you don't have HDMI/DVI-HDCP you will only get down-rezz. the reason it often costs more is that many manufacturers are using it as a feature to differentiate between models with other improvements in the package.
