HELP....I've studied alll of the posts regarding inputting your own IPTV playlist into the mini. Cannot get anthing to work. Used TYPE:4 style, used "group_channel_etc. and nothing works...I go to "internet tv", push OK, push green "upload" button, insert USB stick, recognizes it, highlight file, push OK....and NOTHING.. Have spent hours trying to reconfigure the files on notepad and nothing works...Please if anyone has had any success loading IPTV files into this box. Thanks in advance for any assistance...
