DVD recorder is recognized by program but when burn process starts and shows that it is processing there is no light on my disc recorder and when the process is complete there is nothing on the disc. Using a Samsung laptop, Intel processor i7-3635QM CPU @2.40 GHz 8 GB ram, 64-bit, Windows 8.1; Memorex 8X DVD multi-format Recorder External. I made an iso image of the project but after 2 hours, it said it had a formatting error. I have not tried to burn the iso file to the disc. I have made multi-slide show projects in the past but never with this particular computer. Slideshows were made in Videowave. I tried to burn a single slide show and got the same results (ie. nothing on the disc).
