I had some serious adventures with this so writing them up seemed like a good idea. Mostly this is an intro to the diffs below... I started with the excellent directions on the wiki - http://knoppmythwiki.homelinux.org/index.php?page=MythTVBurn_Scripts_HowTo I've added some troubleshooting notes there as well.

My first problem was that the script would hang while extracting thumbnall images for the menus. The "nigelpearson" fix of changing the options to jpeg2yuv didn't cure the problem, it didn't seem to hurt, but it also didn't seem to help. I finally tracked the hang down to the "transcode" utility. I upgrade that to the latest release (0.6.14).

After some hacking I got through the whole process and discovered that 1) peoples faces were blue in the thumbnails (caused by a known red/blue channel confusion) and 2) the thumbnail images were upside down. Both of these are known issues with transcode with documented work arounds (the -k and -z commnd line switches).

My final problem was sound skipping on DVD playback. I suspect my audio capture settings may be partly to blame here (I just use the defaults), but switching from replex to multiplex works for me and the fairly large number of existing recordings waiting to get burned to DVD...

BTW - To test the ISO image before burning it to a DVD I use the following trick:

Code:

xine dvd:/myth/mythburn/DVD/VIDEO_TS/

It saves both time and DVD blanks to be able to check that everything looks OK before firing up the burner. ;-)

OK, without further ado, here are my (slightly cleaned up) diffs against the current MythBurn CVS (ignore the /myth/mythburn/mythburn -> /myth/mythburn changes, they don't really affect behaviour. The extra level of directory just seemed silly to me):
