I'll refine my question. The blu-ray ready videos were developed by Vegas 8 and are capable of being burned to blu-ray discs by DVD architect 5. One answer above says no but the other implies yes for some systems. I'd like them to be Blu-ray format discs.
Last PM I gave the blu-ray rendering a first shot. Rendered the m2v files and the ac3 files, imported them into DVDA 5.0 and burned a 12 minute set of videos onto a DVD+R disc. It went pretty smoothly once I figured out that the property setting for the DVDA file needed to specify that I was creating a B-Ray disc with 25GB capacity (not 4.7GB DVD). Once I did that, the ISO file rendered fine and I could still burn it to the DVD disc.
The playback was flawless. I was actually stunned...
"I have some blu-ray ready videos of less than 4G. Can these be burned to DVD- or + R media and play on a blu-ray player?"
Yes, it can be done. But be aware that the DVDA generates 002-BDMV-structures.
"PS3 for sure and some set top players."
There is a clear issue: the PS3 ist not able to playback 002-BDMV-structures from DVDs - but will be abel to playback such strucutures from BD-R only. What you can do is to generate 001-BDMV-stuctures, so called AVCDH-DVD - but that can be generated by tools like Uleads Moviefactory 6+/7, but not with Vegas or the DVDA.
Other players are able to playback 002-BDMV from DVDs, too (for example, my Samsung 1400 can do so, but has limitations in the datarate from side of the loader).
