True.
IF you are recording your own voice, etc., in your own voice recorder, you can adjust the bitrate to make the file smaller.
But that would involve too much work.:)
It's easier to just use that site, for quick and simple wav files for remote.
But that site doesn't specify what bitrate those wav files are made at?

But even so:
Image files , you would assume, would contain more info, and be larger.
Or it just maybe how the remote deals with them vs wav files.
It would be nice if it released the wav file memory space after playing a wav file, to help conserve ram.
But that may not be possible, or too much for URC to implement in firmware.
Until then, we need to be awhere of the LIMITED use of wav files.
For everything else , the remote seams to handle setups with tons of devices, pages, and jpgs(on my remote at least), eficiently.
