NBC mulling legal action against TiVoToGo

I find NBC's beef against TiVo for letting people transfer digitally-recorded programming to the PSP and iPod comical. There's a healthy dose of DRM to prevent file-sharing, which should be the main issue, not the copying of content. And when programs are copied into portable devices, the ads within remain intact, barring the user forwarding past them, What does NBC look to gain - a gag order preventing DVR capturing of its content?

Methinks the network doth complain too much. This is likely more a concern over rendering NBC's future plans in the VOD space obsolete than a genuine concern for intellectual property.
