This is ironic but the cheaper the DVD player you have, the more likely that the burn will work fine. You can check this on BJ_M's site dvdrhelp.com with typically reliable information for most makes/models of set top deck. Heaps of other info there too.

PC based players can also tend to be ok with such a disc. What you are creating is quite well known as a cDVD, cdDVD or miniDVD although none in themselves are worldwide "consumer" formats.

(the differences between cDVD, cdDVD and miniDVD come from the degree of variation in the spec from what you'd tend to see on DVD, VCD (or SVCD). Different articles you read specify different defaults and limits for each. Many limits vary and limit the so-called specs even further by having set top CD based video recorders with a certain technical capability which dictate the modes. Like with DVD's you make or buy, the quality does vary. What you are maknig is probably best described by cDVD, in case you want to label it appropriately)

You need to prepare the files in DVD-A, then burn using another tool, such as what came with the burner. e.g. Nero, ISO9660 mode is normal, not using Joliet extended length filenames is also normal.

I'd be fairly keen to avoid these types of authored disc unless you don't have a choice. Rewritables are the best way to deal with shorts when you want them on a shiny disc without waste.
