bockbier , Bugmenot-User bought his player from ebay.de, which is not the same exact Glacier that uxcell is selling. It is just a Glacier look-alike. As mentioned by Bugmenot-User in his other post, he/she also said that it was a Glacier look-alike from uxcell.

The Glacier from uxcell may play .ogg files, but the "Glacier" that Bugmenot-User has may not play .ogg files.
Every player even if it has the same exact casing and interface, usually has different electronic components installed. So some players have the capability to play .ogg whilst others could not.
