Upgrade my O!Play HDP-R1 from 1.38N to 1.41N.
1. Fix the issue that in photo grid view mode, only first BMP picture will be shown correctly, the rest BMP files will be shown as question marks.
Fix the HDD hanging issue when plugging external Buffalo HDD into O!Play.
I did not upgrade to 1.39, but direct upgrade to 1.41 from 1.38.
