I've created over a dozen DVD-R HD discs from HDV .m2t captures using Womble MPEG-VCR v3.14, Ulead VS10+, and Nero 5.5.10. I use various menus within VS10+, including the supplied HD default one, the default one from MF5 that I copied over, and others that can be downloaded for free from Ulead. I create chapters and even use .mp3 sound bites on these menus. It takes a little longer for to create the HD folder, but I think the added menus and chapters polish up the final product and are worth a little bit of up front time and effort. It's really very minimal.
They all play, but I do get various results and haven't figured out a pattern yet. Sometimes they work without a problem, other times I can't get the HD-A1 to navigate from the main menu to the content. It may have to do with which menu I work with or if I include chapters and chapter sub-menus. However, the good news is that these discs always jump to the HD content and play if I select STOP and then PLAY. It's never failed yet. So, what I thought might be a coaster works with this easy work-around to any menu navigation issue. If anyone else runs into the same problem, try this first before tossing the disc.
