EDIT - yeah - for your DTiVo the only solution is the "noscramble patch"
Are you saying unscramble.o won't work? By my reading, the noscramble.o module prevents scrambling, but does not allow the transfer of previously encrypted recordings. Or were you speaking of the kernel hack? If so, the same is true of the kernel hack, isn't it? From my reading it seems to me unscramble.o won't work with the kernel hack, either, or am I mistaken?
