Sorry for the nag.. :-), but I urge you all to have a look at the scrips in the
CVS for mythburn (http://sourceforge.net/projects/mythburn/).

Although the package is driven by MythWeb addon scripts, the scripts
doing the work are just ordinary shell scripts. In my experience, the
php fronend has a high WAF, but a QT frontend calling the scripts
would be a very big bonus. Having to start up two computers to be able
to burn a DVD feels kinda strange.

Furthermore, if the ready-to-go scripts are used, there will perhaps
not be a need for two types of burning... it comes from the good
nature of code reuse, open source and not re-inventing the wheel where
there is (as I understand it)  no need.

I just looked through this a bit. I must admit I haven't tried it, but as far as I can tell from reading through the code, it starts out by demuxing/remuxing the MPEG stream. That will break audio sync on arbitrary ivtv captures.

The reason for suggesting two types of burning is that there really are two separate reasons.

1 (DVD archive): Cut out commercials, possibly denoise, downsize on a transcode. Make the result with menus, multiple episodes, etc and playable on a settop DVD player. A very hard problem, considering that the backend tools are not 100% reliable with A/V sync

2 (Mythtv archive): Dump any recorded content in the database to a removable medium, including any database information as an .sql stub file. Easy to do, and allows for archival without *any* generation loss or manipulation of the stream at all.
