I was getting pretty frustrated that a lot of the .avi files I was getting were refusing to play...actually they would play but on;ly a blank screen would appea I D/L GSPOT after reading a post on a now dead, sililar thread and it pretty much confirmed somethings I was thinking I THINK. FOURCC "0" doesn't refer to a codec, it refers to the lack of needing one, although the file said it was enccoded in another codec, it also said it doesn't need one (I got kinda confused on that point. BUT then I looked at the audi section which showed NONE was used. I had earler looked at the files properties and under the advanced section most of these files showed something like a 3 or 4 FPS, and really low bit rate. While Gspot made it all clear I now see I didn't really need it, a file encoded in 3fps wouldn't be very interesting now would it..Now if I think for the most part I can just use the properties section of a file (right clicking) to check instead of going through the hassle of opening Gspot everytime. I'm still keeping Gspot (for other things it's quite handy) though. AM I right? Does really low encoding properties indicate a file is bogus????
