Not true. If it were capable of delivering more, they would not
have needed the new laser band or tighter tracked, higher capacity ,
higher data rate discs and readers.

It MIGHT be capable of delivering a little higher data rate, but the
space would run out before the end of the flic, and you would have to
have a flip disc to hold it all.

So the fixed pixel rate was chosen for many more reasons than simple
legacy compliance, or ONLY legacy compliance. Many factors were
considered.
