Print to DVD greyed out in 4.51c

[Stereodesign Senior Member Find all posts View Profile Close Stereodesign]

Just updated 4.23 to v4.51c and everyting was fine, TM Pro, Quick Titler import via 1394, old projects opening, all working without issue, until I tried the new DVD from timeline only to find the option greyed out, I have a blank disc in the drive ready and am doing everyting the manuals say but it just remains greyed out.
Anyone else had this and found a solution?

is your project setting a standard definition DVD compliant setting?

Threse are what I see in the Project output settings.
I don't know what the Additional Info : HDV bit means as the video was SD DV.

change your project setting to something interlaced like 50i bottom field, then it should work

all non DVD compliant presets will appear grayed out

Even though I have a NX card installed I cannot get any output settings except with the OHCI SD PAL.

I'm doing this via Settings > Project Settings > Change Current Settings

maybe your source files/project is not suitable to be changed to interlaced on the fly?

what was the original footage and project setting at the capture stage?

Capture settings. SD mini DV
