anyone has had any problems with sony tapes with the optura Xi? I've heard the use a lubricant that may gum up non-sony camcorders. The price of the sony premium (DVM60PRL-blue package) is similar to the Panasonics or Fujis, and i guess the premium type is better. Should i be concerned about the lubricant issue when used with the Optura Xi?

Thank you for your help
