anybody burning BDMV images to DVD-r out there?  is it working in any players?

[Tvjohn]

Yes, tried a couple of disks.
HDV from Canon AH-X1.
Have also used Pinnacle Studio 11 to do this.
Crazy long encode times though...

Tried to burn the image out of DVDit rather than Nero. player says can't play disk.
Studio 11 disks are dead reliable (AVCHD)
This should work better.

Ok.
Creating a volume rather than an image and using nero rom to burn a udf 1.02 willl play
but stutters badly..
will try one more with different bitrate settings, studio has a max setting of 17mbs, will try that and
compare, as I have an example of the same media done in STUDIO AT THOSE SETTINGS.

Another disk, encode settings VBR 30m max, 17m target, 10m min.  burned nero udf 1.02
took around 2 hours to encode and create voulme.
Significantly more digital artifacts than Studio 11 burned at the same rate.
In the defence of DVDit, outputting a disk takes one fourth the time that it takes Studio to output.
Still, the quality does not match compared to equal bitrate settings...

I've been putting my short projects on DVD+R for some time now.  Short is 50 minutes for dual layer and 25 for single.  I burn to a volume (ie disc folders), and use my burning program to burn just the BDMV folder (since I have a Sony player) and take care to make it UDF 2.5 format like my regular BluRays are.  My Sony BDP-S1 identifies the project as AVCHD, even though it DVDit only does mpeg2.   I feed DVDit Pro HD my Cineform Access HD .avi files and let DVDit do the encoding.

I have found you have to keep the bit rate to no more than 20mbps to get smooth playback.  Ive used VBR and 20 average, 25 max and 13 minimum but found some jumppyness on the few parts where only something central (the speakers arms) were moving and nothing else.   Now I just use CBR, constant at 20 and the results are just great, no different from real Blu-Rays at CBR 25 (HDV2, 1080i native bit rate).

Interesting, I have both HDDVD and Bluray players, and trouble (stutter) occurs on the HDVD when you exceed 20mbs on that as well.
