True - the problem is only for 180p24, so if your hdtv isn't capable of 24fps it won't matter to you.
According to the thread on the forum there are a lot of other small annoyances that the 2.0 supposedly fixes - but not 100% One report has load times and drawer opening/closing is faster??
"Reports", such as those are like opinions Wayde (imho)...meaningless without precise timings for each fw. The best I heard (confirmed) was like two seconds quicker with 2.0 from start up to play.
As a note: this is all meaningless unless one has a 1080p/24Hz display. That is, if one does not have 1080p/24Hz capable display, one would not need to use the 1080p/24Hz setting, and can avoid the 2.0 fw jaggies altogether. Additionally, one can use the 1080i setting on the player, and allow their display to deinterlace. Finally, as noted above, one can revert back to 1.3 fw if one so elects.
So the issue with 2.0 fw is finite, and workarounds are available (unless one insists on 1080p/24Hz setting w/ 2.0 fw), and the benefits may outweigh that one finite drawback. I myself am considering it. But as you wrote, the advantages are not yet all that well published (additional menu options, slightly faster load times, and the big one for me, less finickyness with playability of discs). Cheers
