the cutlist is created by the commercial flag process. and if you use the aforementioned utility you will just setup an automatic transcoder, or better yet just edit the cutlist as specified earlier in this thread cause it may eat much of your show otherwise and start the transcode process by hitting X. I am not sure where the cutlist is stored, but you can obviously sent it to an external script as nuvexport can use it if you tell it to. but in the case of the aformentioned program/script/plugin (whatever you want to call it) it integrates directly into mythtv and takes the place of the normal mythtranscode (at least from the way I understand it.) maybe you should read the wiki page he mentioned.

I don't know if it will work for HD, but if you give it a try and it doesn't, chances are we will be able to get it to work. Originally, it didn't work for PVR recordings, but with a bit of feedback I was able to modify it so that it did.

If you insert a delete after cutpoint in one of the first 25 frames, it will keep the original recording (although it will be given a new timestamp 1 minutie older than the original time. This was to prevent mythtv removing the recording and the recordedmarkup info when commercial_cut is used in place of "transcode" and when it is initiated from the mythtv interface).

You can't enable any more logging than it already does.

Watch the recording in mythtv. press e to enter edit mode (or m to bring up the menu and select Edit Recording). Then Page Up (or is it down)? until you get to the start of the recording press space and you will be given a list of options one of which will be "Delete after this frame" or words to that effect. Select that option.

Place other cutpoints as required.

There is a key you can press to load the comercial detection marks as a cutlist which you can then modify (this will probably remove your delete after cut in the first few frames so be careful). There is also a key to remove all cutpoints. Refer to the mythtv documentation on keys.
