My understanding of the blog was that only a few codecs (DV and DVCPRO) will interpret footage in a way that doesn't result in a yellow bar.
- yellow: The source media’s codec is computationally difficult (such as AVCHD). As mentioned above, only very few simple codecs don’t get a yellow bar; these include DV and DVCPRO.
So even when creating a sequence from an imported clip, the chances are that unless it is DV/DVCPRO footage, you're going to get a yellow bar.
I have had exactly the same issue... but blessed with a fast Mac Pro machine, it's not too much of an issue.
I do agree though that it is misleading...
