Two part post here, first of all Olcay has released a new version (beta 4) of his 10-foot MCML DVR-MS editor.  The release is mainly because of a timebomb in the last release, so if you currently have it installed you should grab the new release if you wish to continue using it.

On a related topic, it appears that TV Toolbox is able to edit content recorded from CableCARDs.  This according to a user at The Green Button who says it works for all his recorded CableCARD content including HBO HD.

I’m personally shocked at this, but don’t have a CableCARD PC to test it with.  It doesn’t output the content in an un-protected format, but if true this means you could cut commercials out and if not patched gives hope for an automated commercial skip solution (though my guess is that would still be a huge undertaking).

I'm not sure why TV Toolbox is able to edit this content, but I don't think there is anything specific in the application that would allow it to work.  The developer, Olcay doesn't even live in the US where the content originates, so I’m a little confused here.
