As much as I like DVD Architect's interface, it remains unusable for me. Why? Because it doesn't take files encoded with x264, which is by far the best h.264 out there. The reason for this is that DVD Architect doesn't support interlaced footage that has been encoded with MBAAF instead of regular interlaced mode. x264 only uses MBAAF. So I wish I could use DVD Architect, but for now I'm forced to use Encore CS5.
