Hi, csu1970. You posted in the photoshop elements forum and very few of us use PRE. It has its own forum and you'll get better answers there. I'll move this for you.
As per the discussion to which SG directed you, you do have one perk in your 25 menu marker limit situation in Premiere Elements 10. That is, at least the Premiere Elements 10 stops you from adding the 26th menu marker; whereas, in Premiere Elements 11 you can add menu markers way in excess of 25 only to find out that you only have just 25 menu markers recognized.
