I use a public computer, so need to have a dvd burning software on a thumbdrive. Or use a free online site that can do it.
I have tried the following portable apps from this site
Infrarecord portable: error code, in 2 seconds, on every file I try to burn. MP4 and VOB
cdrtfe portable: error code every time I tap an app tab, file error, dvd error, cd error. And it will not allow selection of source location.
