Well if you can FTP do this
Send in by ftp the bouquets and service files all the files in the folder except the satellite.xml to /etc/enigma2/
Send the satellite.xml to /etc/tuxbox/
Restart and see if they show.
I succeeded to to ftp user bouquets, but there is sill a problem with satellites.xml and lamedb, no way to ftp them, i used filezilla and flashxp.
