I use Ext2fsd to connect my popcorn hour A-200 via USB slave for file transfer in Windows 7. Since updating to 0.50 I find that the files I transfer to the internal drive either do not load or load and then hang immediately.
Observations using Ext2fsd 0.48:
File transfers at 30MB/sec
mkv files play no problem.
Observations using Ext2fsd 0.50:
File transfers at 65MB/sec
mkv files either load and hang straight away or don't load at all.
I have reverted back to Ext2fsd 0.48 for the time being.
