I noticed the issue with my release but thought my eyes were playing tricks on me. No, it's not an NTSC issue because the version I made with TMPGENC is fantastic and doesn't have the same flaws.
it was a flaw with HDTV2DVD. In fact, I sent all my info to it's creator and I won't be using it any more because of it.
And in regards to your smart-ass comment, there's a BIG difference between something that is overall crap and what I released. 98% of the people who downloaded my version of BR didn't notice a problem.
