Decrypting Transport streams from Japanese DTV

Unfortunately, my strategy fails, but not for the reason you might suspect.

The blu-ray recorders record in a slightly different format (BD-AV) instead of the BD-ROM that hollywood movies are. Both have AACS encryption. It seems, however, that AnyDVD only works on BD-Roms, and not on BD-REs.
Also, there were "other" tools to decrypt BD-AV discs which had AACS V1-3, but of course now all the recorders have switched to BD-AV AACS V4, so there are no tools for decrypting them for the time being.
PowerDVD can play back the discs, however, so it's only a matter of time till someone hacks this too...

That's too bad. Always something to catch us out isn't there?

Basically you get collections of 3 files, a .dtv, and .dtv.meta and a .dtv.rat
The .dtv.meta seems to contain data about the broadcast, the .dtv file is the large one that I think is encrypted somehow, and the .dtv.rat file is probably the key.

Not promising anything, but could you grab a short commercial or something and make those files available to me? If not myself, then I know a few people who would be interested/know something about this kinda thing.

Thanks.
