when I about to use it to convert, I notice that different source files would give a different expert setting than what's on the guide here. So my question is do I use the settings outline in the guide here, or should I keep the settings that are there as soon as you load the source file. Another question I have somehow I made some conversion with TMPGEnc and those made at 29.97fps, would not play in my dvd player after burned. But if I converted it at NTFS film 23fps, then it would play fine after burned. Why is this? Please help.
