I was having a horrible time previewing and printing to tape! Everyone made some great suggestions on the forum- but nothing worked---until I discovered the problem! I edit a weekly TV show and had current digitized files on my system using VV3. When I tried to use these VV3 files...my problem kicked in! V4 does not like the VV3 flavor of AVI!!! When I captured new footage- worked like a charm, and V4 previewd VV# MPEG 2 files to my external monitor!! This is a problem for people who use VV3 and V4 for a living! Can SoFo look into this and recreate the situation and hopefully correct the VV3 to V4 issue. I have "seasons" of shows stored on raids because the shows get customized for different sponsors!! This is my issue- all that work can only be re-edited on VV3---> this is horrible and hopefully can be fixed! Please!
