Same results show with a Reaper Cue/Bin

The Red Book standard requires 2 seconds gap at the CD start. So the first track's (INDEX1) offset must be at least 00:02.00. Of course this offset can be much longer, and the audio before it is considered as hidden pre-track.
I don't insert 2 seconds of silence before the audio part, but I leave this to users, to have full flexibility about this hidden pretrack, even if it is only 2 seconds long. This allows the exported files to have completely the same time offsets as they are in Reaper.
A lot of other programs always insert a 2 sec silence. That's why there are differences and their values in DDP files are 2 seconds later than actual marker times in Reaper.
With my export, you must manually position the tracks so that the first track is at 00:02.00 offset. If you do that, there will be no differences. But if you don't do that, you will loose the first 2 seconds from the first track, as I move the INDEX1 marker and thus shorten the tracks by 2 seconds. This is clearly visible in the screenshots, where the first track is 2 second shorter in Reaper.
But, just to prevent further issues with this, I will also always insert this 2 second gap at the beginning, independently of the markers and audio position. This will allow you to position the audio tracks directly to the beginning, without worrying about 2 seconds silence.
