[jose martin] "I was trying to render my project per instrucctions found on other posts in this forum, using the Bluray Main concept 1920x1080-60i template, but my sony vegas movie studio platinum 12 does not show that template."
I would recommend that you uninstall and re-install Movie Studio Platinum 12 because my copy definitely has the
Blu-ray 1920x1080-60i, 25 Mbps video stream under
MainConcept MPEG-2. Yes, you can change your 1440 one to 1920 width but you should already have this template so that's not a good sign.
