text: I think you will find the problem could potentially be the type of disc that you used.  There are two camps of manufacturer in the DVD world - the +version and the -version (such as Panasonic) which means a DVD-R will not play back in a +manufacturer's machine as they are incompatible.  Although this is being improved it is something that a lot of people are unaware of.  I am sure you can play your DVD-R recording in another -R machine but obviously this doesn't really help.\nI would suggest you upload the footage to your computer and then save that file on a USB stick.  Then take that file to a +Recordable computer and re-burn the disc.  This should then work...hopefully.
