I have been using this version with the patch successfully. The one 
feature that would be nice is to look at the total time of the selected 
shows and if > DVD length (4gig?) transcode them using a different 
bitrate to make the shows fit on one DVD. This wouldn't normally be used 
for just putting one 2hour show on a DVD, but I have a bunch of 30 
minute shows I would like to put on a DVD for storage and don't care if 
the quality is reduced some to make them fit. Kind of like what 
DVDShrink does, but done as the videos are being processed with remplex 
instead of after the DVD has been authored. There are some formula's on 
the web for calculating the bitrate to make them fit on one disk, but 
I'm not sure if ProjectX can be used to reduce the bitrate or if it will 
take another step somewhere.
