Sorry, but your dl-link just leads to a 168byte file that can't really be opened. What worked for me was http://www.samsung.com/sec/consumer/...&menu=download
And if i compare that with the known infos and R1 manual i get the following:
+ New/Changed: MP3HD, 40h Playback, micro USB, Sound Alive (instead DNS), Music Square, 24h clock
- Missing: TV-Out, Bluetooth, Flash-Player, games, Datacasts, Adressbook, (Still) CardSlot, FM Receiver bit worse quality, bigger display but same res.
So it seems to be more music related than anything else
