I agree with you it shouldn't be there. Correct me if I am wrong on this point but TiVo was most likely forced to use DRM in their files in order to use allow the legal use of cable cards in their DVR. Fortunately not many channels are flagged for copy prevention. As far as the ease of copying TiVo desktop and Desktop Plus allows someone to download from the TiVo unit and then convert it to video that is playable on an iPod, iPhone, several blackberry devices, Palm Pre, Zune, PSP, and several other devices. As far as burning them onto a video DVD or Blu-Ray it does take a few additional steps. Start off with either TiVo desktop, TiVo PLaylist, Galleon, or any web browser to download the video or videos, using either Tivo Decode or Directshow Dump to remove the wrapper, then use any DVD/Blu Ray authoring software out there as long as it supports MPEG2.
While it is rather easy not everyone would be able to perform such acts. Then again, those who have little or no technical skill probably were not able to set the clock on a VCR, or copy a simple file on a computer. No matter how easy you make something there is always going to be quite a few people who will not simply get it.
