mate u dont ftp the extra url lol. You open extra url and type the box ip address and click send or something like that.
And yes that will be your problem mate every image need a burn.bat file otherwise it wont program.
ALSO
you dont NEED to use extraURL. You can use ipk in this threadhttp://linuxsat-support.com/gi…14877-cccam-openmips.html and ftp file to tmp folder and install it using sat box or use install ipk option on VU Control Center
