Why is my insignia tv remote interfering with my dB power portable DVD player?

While there are a lot of frequencies availabe, It is possible they both are using the same one.

I have the problem with my Remote Rotor TV antenna, and the Sony Sound Bar.

We are lucky, with some systems the Microwave may also interfere with the signals.

Some remote command signals are very similar.

Can't be permanently cured.

Try aiming the remote so it doesn't happen.
