This looks ok. DVD-R, closed, two sessions. The operating system has the
choice. For an ISO 9660 filesystem it would read either block 16 (session 1)
or block 1067120 (session 2) and then dive into the respective filesystem

The non-relation of first and second session should make no
difference for the choice of session by the reader.

Did you do anything to let session 1 appear more attractive to MS-Windows ?
Like giving it a Joliet tree by genisoimage -J ... (just a wild guess).

Before you rely on that, you should first try to find out what is the
officially intended behavior of MS-Windows in this case. (I failed to
find an answer by Google.)

Have a nice day :)
