I've just installed 1.61 beta but had to go back to 1.6 because I can't see anything on my SD card.
Initially everything was browsable under folders, but when I scanned the card but it hung at 21918 tracks. I did a hardware reset, went back in and nothing there, in library or in folders. The "About X1" menu said the card was pretty much full but there was no music files. I tried another card with music tracks on and that too showed zero tracks!
Reinstalled the firmware but still no joy. Just gone back to 1.6 and all looks good again.
Tried the entire procedure again:
1. upgrade to 1.61 beta - all files there under folders, play fine too - love the search feature, saves loads of time, especially if media library would work

2. update media library (which is much faster now by the way

) - it hung again, this time at 21899 tracks

3. ... I waited a full 10 minutes just in case ... still nothing

- did another hard reset - however, directories and files still visible this time.
4. swapped the memory card and rescanned with 572 tracks - all works fine :s
It looks like there either there is a memory leak in the code or the memory is simply full when a large number of tracks are in the player.
Anyway, I'm off back to 1.6 and waiting for the next release - hope it's soon because the media updating and search are major advances for me on this DAP.
Keep up the good work
