Hi,
the DM7025 version (today's build) is currently in a pitiable state. Actually, I think it should be set to "Red".
(1) The nfi itself is broken. After unpacking, you get errors when doing a "ls /usr/lib/opkg/info/". I worked around this by reinstalling all packages listed in /usr/lib/opkg/status.
(2) The enigma binary is not up-to-date with respect to the packages that are downloaded by opkg. OpenWebif complains about not finding "Tools.Alternatives". It is not "linked" into the binary.
(3) Searching channels does not work for DVB-C receivers. I get "cableTransponderSearch finished 127" (as already described in http://pastebin.com/U98VUGwH). Not that neither the "general search" nor the specific cable search works. The package "dreambox-blindscan-utils" mentioned in "http://openpli.org/forums/topic/23831-dvb-c-scan-werkt-niet/" is not found by opkg.
