ORIGINAL: Termyn8or They don't like old technology. I have an SL-HFR60. It's right before superbeta came out and the reason it can do what it does is because it has better dynamic range in the video channel. This makes an RMS level detector unnecessary which is what macrovision et alii affect adversely to prevent making a good copy. I had an SL-HFR70 which cannot do what the 60 does. The 60 and the HFP-100 that enables the hifi sound came to about $550, and this was when money was worth alot more. I have studied copy protection schemes for a long time. Before digital I could also beat any cable scrambling technique. I may have mentioned BMAC which was among the first of the digital scrambling methods. They started winning the game then. It could be beat but the board to do it cost $11,000. It was just cheaper to pay for the material. The music industry has a long way to go. First of all the process is so much simpler, and high quality is not as hard to achieve in the analog domain. The sound card in most of my PCs put out a signal just as good as a CD, and MP3s at 160K bitrate or higher are indistinguishable from the original, at least to me and I used to have almost golden ears. I still hear pretty well though and I can't stand shitty sound. I won't even bother with a 96K bitrate MP3 because it grates on my nerves. There are very few exceptions, and those are material I really want and I just can't get a better copy. Those little MP3 players, in the early days alot of them converted everything to 96K to save space. Now comes iTunes and iPods. My sinister has one but will not install the software for it because it would lock her out of using it for just about anything I can get. Of course that does not keep her from using it in the analog domain, but that means it all happens at 1X. An hour of music would take an hour to copy. Now even in the old days when digital satellite radio first came out, they said you could make a copy on a CD, as CD recorders did exist. But the music would have like a digital watermark. You could have it for your own use like in your car or something, but your personal account would be tracable. That means if you make a thousand copies and sell them, you could get a knock on the door. Some companies also asked when you ordered a PPV movie if you wanted it for watching or recording. Watching was cheaper and they did find a way to prevent rcording. They changed the frame rate enough so that VCRs could not lock into the signal. However I could modify the servo cicuit in them and get it to do it. That would NOT make the recording copyable to another tape, and unless a bunch of time and effort was put into the modification, the VCR would not be able to record normal videos. While I'm sure you like technical information from time to time, alot of this is useless today. But it does quite illustrate the point that this war has been going on for a very long time. T^T Yeah, or pony up the bucks for a real timebase corrector....
