ok this isn't another topic about ntsc dvds, but dvds in general.
occasionally, ok not occasionally, frequently, when watching any dvd using the ms dash or thc or xbmc etc, i get white flickers appearing in the picture. it is strange because when i rewind the dvd, the flicker is still there, like it is embedded into the picture. this means it isn't a problem with the connection between my xbox and tv. could it possible be dirt on the dvd? or is my thompson drive buggered?
