CableLabs recently approved the DTCP encryption standard, which may be what TiVo uses. "These features will provide support for video transfers between Series3 & Series2 systems and between a Series3/Series2 system and a PC. High Definition content will not be supported for transfer or playback on a Series2 system (Series2's just can't play HD), and copy-protected High Def or Standard Def content cannot be transferred (same as our current Series2 products)," detailed TiVo team member TiVoPony in the Community Forums.
While standard definition content rarely includes a copy protection flag while during broadcast, the same may not apply to high-definition content and some TiVo users may find they are more limited than expected in sharing HD content to other TiVos or PC. "If it's recorded in HD on a Series3 or TiVoHD, then it can be shared between those platforms, but not with a Series2," added TiVoPony. "And when I say 'can be shared between those platforms', it of course comes with any caveats the copyright owner dictates regarding sharing."
