DirecTV (and similar companies) take some pains to prevent what you are trying to do. The providers of the programming prefer that their programs are not put on DVD or on the internet, and DirecTV (and DISH etc) attempt to prevent this.

For example, the stored programs on integrated DVRs are encrypted. Some DVRs allow multiroom viewing (and DirecTV's DVRs may do this soon), but none will readily allow you to burn them to CD or DVD.

To watch on a computer over a network Slingbox will do the job, but only in standard def. Hi-def requires rather a lot of bandwidth. And you still won't be able to record to CD. Slingbox will also let you watch on a remote computer, even in another country, although the quality depends on your home uplink speed.

The only way to capture content from most DVRs is to use the analog video out to either a computer capture card or a CD/DVD recorder. Again not high-def, though.

Good news, though: streaming music from your computer's storage TO a DirecTV DVR is supported right in the box. You need to get server software for the PC, such as TVersity (free download). But then you can listen to all your music on your TV audio.

Hope this helps.
