Stan Thanks For Your Help.
I will be paying attention to those settings, I did a project this afternoon, (see above note) Encore was busy taking my 1080i down to 720.
Does Encore change the time stamp on the files .WAV or .m4v files. I notice some later files, from last week Media Encoder created, the date modified was different on each, where the file should be only a minute diferance these are now several hours off. ??
