Hi. There is a change in focus by the laser for a dual layer DVD - the laseer has to read through a semi-transmissive layer for that extra information too. Cleaning your laser lens with a cleaning disc kit may bring it bck to life especially if you smoke... else could be time for a new laser(s) https://www.bandcds.co.uk/faqs/dual-layer-dvds

If your remote won't work at all, then you'll need to get a new remote from Samsung to control all functions. If however, everything works on the remote but the volume, keep the original for all other functions and just use a cheap universal remote programmed to the Samsung code to control the volume. I had the same thing happen on a Sony THIB remote for a HT. I used a Scientific Atlanta to turn it on and off, as well as control the volume, but retained the original remote so I could get at all other functions. If you have to buy a new Samsung remote or if you buy one of those high-dollar universal remotes that program a zillion functions it will cost you big. Fair warning.
