I read the reviews here before buying the player. The main points I gathered from those reviews were that the player had great sound, but a sub-par UI (this I can live with). I did not know about the music file tagging ,sd card compatibilty, or unit freezing issues. The bottom line is- the player does not deliver on some of its advertised features- ie SD card compatibilty for one. NOWHERE is it mentioned on the Noisy Motel site that I would need to play around with mp3 tagging programs to alter all the file names in my music collection to get this thing to work. This is not advertised as a niche product that requires further programming for it to work. It is a consumer electronics product. If I bought a Sony PS3 which didn't read Sony games discs without first altering some aspect of its soft/firm/hardware I would be entitled to return it for a refund.If you advertise SD card compatibility, then you should make sure that SD cards will work with your product, or provide some sort of disclaimer to say that it may not, and why. In any case,as I mentioned earlier, none of the remedies Noisy Motel suggested have solved the issue.
