Avast Pro and File System Shield probs

Rig is i5 Intel with 16 Gb RAM, Samsung EVO 250 Gb SSD running Win7 64 bit and Nvidia Geforce GT610 6 Gb RAM. Problem = when using Indigo Rose Autoplay Media Studio v8.0.3.0 creating DVD containing WMV video and exe files for installation of freeware applications, Autoplay Media Studio will not preview or create package for burning unless Avast File System Shield is turned OFF. Current version of Avast Pro is 11.1.2241 with virus definitions version 151126-1 as at 27 Nov 2015. Previous versions of Avast Free lived comfortably and played well with all my installed software.
Any suggestions ?
