I feel your pain!

I haven't explored my really old DVD's yet, but my commercial CD
collection seems to be unaffected by deterioration.  Among the very
first CDs I bought was Roxy Music - Avalon in 1982.  My copy is
manufactured in Germany.  It has outlasted 3 CD players over the years.

The plan is to produce lossless copies of my collection to gain the
convenience of searching for songs and creating playlists.

The added benefit would be a sort of "backup".

Might be wise to consider the same conversion strategy for the DVDs that you
can still play?
