R, so you want a DVD reader... and how to make use of that proprietary data... what data do you want off that Sat-Nav DVD? It won't contain your saved locations or trips or anything you accumulated during the driving of your old car, that will have been stored in non-volatile memory inside the Sat-Nav unit the DVD for it was and is read only, it only contains map data and points of interest and possibly a copy of the firmware for the unit.

TK,
You 'Rock' sir! Why? Because I did do some research to find a ISO or something. It is kind of complicated and confusing what works for my FN2 GT+ Type R with Sat-Nav and at times the firmware/reset or not. The Sat DVD of mine is a Honda DVD disk. The disk got damage to that small layer and the unit doesn't read it. It is accessible a bit with CRC errors, hence why I could try to make a DVD ISO and to burn it. Just complicated, but an awesome reply, thank you!

And yes, it still has my routes somewhere ;)

Colin, And then you can put that USB stick in the USB port of a SmartTV and view the slideshow.

The tutorial on the product site doesn't say much about importing your photos other than you can use drag & drop. Leawo DVD Creator can output the DVD in the requisite 2 folders on your hard disk -- the same 2 folders you'd burn to a disc -- and there's no reason you couldn't copy those wherever you wanted, e.g., a USB stick. Everything you see on a DVD is mpeg2 video, so you need to use a player that can handle that video -- VLC is a good choice for devices running Android, since the native player on most Android devices cannot decode mpg2. That said, nowadays video DVDs are Not a good choice for slideshows -- you're restricted to small, low resolution photos that will not look good at 1080p, & terrible at 4k. Some devices -- TVs, streaming boxes etc. -- have their own app that will display photos on a USB stick as a slideshow, many will let you mirror or cast from a cell phone/tablet, or you might be able to use a web browser to view your photos online as a slideshow if they're stored on one of the cloud sites like Google.

Colin, you'd likely need a 3rd party tool to rip a DVD or DVD folder set into a more technology friendly video format, rather than MPEG2 VOB files of max size 1GBytes each. have a look at VSDC Free Video Editor it has a slide show creator built in and can export to wide range of video formats that can be placed onto a USB stick for use in smart devices including other computers.
