DVD Decrypter breaks DVD-V encryption. But DVD-A was designed with more secure encryption. If it had actually become popular, some hacker may have tried to break it. But with a couple hundred titles out, it remains secure. Sort of like SACD. Never reached a critical mass to interest pirates.What the original questioner is missing is that both SACD and DVD-A were designed from the ground up to be unrippable. The record companies like to blame most of their problems on the fact that everyone with a computer can copy CDs. Maybe it has hurt them, maybe it hasn't. But they hate it.
So in introducing new audio formats, they made sure that ripping to a computer was very difficult. Their hope was to grab market share with a secure format and start the hard transition back to controlling their content again. But they didn't grab much market share.
So SACD and DVD-A remain secure. As an above poster said, if you have a DVD-A without copy protection and without MLP, then yes, you can rip it and probably compress into a flac format. But that's a small minority of DVD-As, hardly seems worth the trouble.

*** But DVD-A was designed with more secure encryption. If it had actually become popular, some hacker may have tried to break it.

At least to the point of being able to rip DVD-Audios onto the hard disk, which was the original question asked.
As for whether this is "illegal or not", i am not an expert in copyright law, but would suggest the legality of being able to rip or copy discs for personal use would depend on the jurisdiction. In Australia, for example, copying albums even for personal use is technically illegal - even recording your favourite LP onto cassette tape so that you can play it in your car.
"At least to the point of being able to rip DVD-Audios onto the hard disk"...how does this work? Did they actually break the encryption or did they find a way to transfer the encrypted and MLPed bits to a hard drive, where some software player can play them?If the latter, there would be no reason to flac the file. Flac is probably about equally as efficient as MLP, anyway if a file is MLPed, further compression is likely to yield little or nothing.
some russian guy wrote a hack to trick WinDVD into decrypting the AOB files and write them out in unencrypted form on the hard disk.Separately, another hack was then written (by the same person) to allow WinDVD to read these unencrypted files, apply MLP decoding, and then write out raw PCM.
As a result, you get 2ch and 6ch PCM files on your hard disk which you can play to your hearts content. You can recompress them if you like using WMA or FLAC or WavPack or Monkey's Audio or whatever.
However, you can't burn your own DVD-A from them because the Verrance watermarking will cause your player to mute the output.
PS - as a result of the above hack, the current WinDVD player no longer supports DVD-Audio playback. :-( But the hack would still work on older versions.
