Wow, Thank you very much! I didn't even realize you, the creator of the app messaged me. XD I just wanted to help a fellow user, because I was struggling with this web server thing myself a few days back.
On the issue:
pPlay lists folders in the directory, but when I press on one of them, it just jumps back to the first item of the list without opening the folder. Streaming works great, but it takes a good 1-2 minutes to even start a my mkv videos. (Not streaming problem, the app basically freezes for those 1-2 minutes, but after that, it works.)
Thanks for the fast response!
