Thanks Devin,
following your instruction for firedtv I've compiled
v4l-dvb-5578cc977a13 but the results aren't so good. After doing an
"make rminstall" , compiling and "make install" I plugged the USB
stick, the various devices were created (including /dev/dvb) and here
is the dmesg output (now it's identified as card=1)

[drm] TV-14: set mode NTSC 480i 0

then I started checking if it works. The command "vlc channels.conf"
works, i.e. it plays the first channel in the list, but is unable to
switch channel. me-tv doesn't start, but I think this is related to the
recent gnome upgrade. w_scan doesn't find any channel.
Analog TV only shows video, no audio. Tried this both with sox and vlc.
When you say that I have to choose the right TV standard (PAL for my
region) do you mean I have to select this in the TV app I'm using
(tvtime, vlc, xawtv) or as a module option? I've not seen any em28xx
option for TV standard, so I suppose it's in the app.
Finally, I've noticed that the device is much less hot than it happened
with out of kernel modules and the card=11 workaround.
Is your latest post "em28xx mode switching" related to my device?
