1. There is no such thing as a 'universal' remote.
2. If the remote's design is earlier than the device you wish to control, no remote can be trusted to have the correct/full function code set for the newer device.
Since the manufacturers reinvent the code set for each new controlled device, the remotes become very quickly obsolete.
Buying a 'learning' remote gives you at least some chance of using your newly acquired device with it after feeding it the codes from the original.
I downloaded the RM -230E manual while responding and I don't even see Sansui on the code list at all so they may have introduced their DVD player too recently for it to even be included in the code table of this remote.
I have the Chunghop RM-L988 and my orphan TV had to be programmed via IR but that works better than others I've had and this model has an 11 device capability. I'm only using it with three, two of which were contained in the factory tables, the third was done with the learning function.
The only flaw I have found after two months of use, is the sloppy mounting of the IR LED which is pushed down onto the board inside and has to be aimed below the controlled device to work consistently.
This versatile model has around 5,000 codes programmed and with the learning function won't become another 'for the drawer' for some time to come.
Under $20.
This manual is from May of 2009 and may differ from yours but, as mentioned, no Sansui:
