Okay, I still can't get it to work.
It no longer chokes on that playlist, but I still get this screen when I connect to
http://empeg/drive0/fids/101?.xml :
My installation steps were as follows:
1) Remove previous-attempt XSL file and the entire contents of the "images" folder.
2) Install Hijack 211.
3) I unzipped the following file (from CharcoalGray99) to my hard disk:
http://empeg.comms.net/files/72165-xmlwebinterface4.zip , using WinZip.
4) It created a "default.xsl" file and an "images" folder with a bunch of files.
5) I uploaded the xsl file to the root of the player and also uploaded the images directory, intact, to the player. Using IE 5.5's FTP-browser interface.
This page partially works. I can send commands to the player and the remote-control screen works. (By the way, I noticed the buttons on the GIF of the remote control screen are in the wrong order. Right is down and down is right. Is this a bug for everyone or just me?)
So what did I do wrong?
