Yes, Nero and Toast seem to "correct" the .ifo and .bup files on some DVDs and the Roxio guy confirmed this.

And yes - it happens no matter if I use the Data Toast DVD or a Video Toast DVD function. And I don't even have to burn to see what happens.

(Actually, the Video DVD function in Toast that I believe was introduced with 6.0.7 is actually just a menu enhancement that also adds an AUDIO_TS folder automatically if you haven't done so already. The actual file format used is the same (UDF). If you are talking about MAKING and not copying a DVD using Toast, then there is no way to compare anything, as Toast multiplexes any files thrown at it and this is obviously not the way to make a perfect clone).

Md5 checksum comparison using xAct or any other md5 tool, or the "compare" function in Toast will show that files have altered, and doing this on any of my Macs generates the exact same results again and again with the same VIDEO_TS fileset.

I said for trading, so that's assuming you already have it burned, make an image of it (the disc), then burn that. That should be identical. Of course you have to burn it initially.
