I use the big 3 to back up my Pal DVDs. DoItFast4U always flags them as Interlaced, TFF (Top Field First), even the extras. I've found that if I follow this, and leave TFF ticked in CCE, sometimes, particularly with the extras, I get the flickering, suggesting that the field order is wrong. After experimenting for months with different DVDs, it seems that if I untick this for every movie and extra, they ALWAYS play back OK. Why is this? Surely some of them REQUIRE TFF to be ticked?? I know I should follow the 'if it aint broke don't try to fix it' route, but I was just wondering! Are all PAL DVDs interlaced? If not, why does DIF4U flag it as so? It suggest that I should tick interlaced and TFF, but this often causes flickering. Also, if I continue to untick everything, DoCCE4U has it ticked as default. Is there any way to change this? Thanks!
