Re: Best Render for 720p & Bluray render question

[John Rofrano] "Not reliably. Blu-ray video on DVD media is not an "official" part of the spec so Blu-ray playes do not have to support it. My Samsung Blu-ray player cannot play those discs reliably. They stutter and eventually stop playing. "

In fact, some Blu-ray players will reject "Blu-ray on DVD" without even trying. Of course, some won't play BD-Rs, either. Like DVD before it, the Blu-ray people didn't really consider the small producer when defining the requirements.

If you can't do BD-R, your best best is AVCHD on DVD. Curiously, while there's almost no difference between Blu-ray on DVD and AVCHD (which was derived from Blu-ray) on DVD, data-wise or structurally, you'll find that nearly every BD player supports AVCHD DVDs. The reason is simple: it's a camcorder format.

DVD Architect can't make AVCHD discs, but there's a freeware tool, multiAVCHD, that can. There are more restrictions than on Blu-ray. AVCHD only supports AVC video and AC-3 audio. You have to encode the video at 18Mb/s or less... that's actually also true for a Blu-ray on DVD to have any chance at working without stuttering, either, simply because Blu-ray players are only expected to have a 2x drive in DVD mode... that 18Mb/s is roughly twice the ~9Mb/s you get for DVD video. There's no guarantee, but this will be more compatible with BD players than any format other than Blu-ray.
