The audio delay feature still doesn't work as intended in Remux Audio. I know ToolKit probably isn't the product DVDFab is focused on currently but hopefully some of the major issues can be addressed at some point, because I still use it quite a bit. Negative audio delay values in Remux Audio should trim the track but instead is muting the track for the specified amount of time. Also, very small audio delay values will result in a broken track on the output file. I tired remuxing with a value of 0.14 and it produced a broken file every time. I changed the trimming so that I could remux with a value of 1.14 instead and it worked every time. I also encountered a weird bug that caused my inputted audio delay value to go down by .02. For instance, I would put in 1.14 and once I clicked away it would automatically change to 1.12, so to get the desired 1.14, I had to actually put in 1.16.
