The test machine I have here utilises an HVR-4000 and AVERMEDIA
SUPER 007.

Multi-frontend works with both adapters with the HVR-4000 containing
analogue, DVB-S and DVB-T frontends, the AVERMEDIA solely DVB-T.

At this time with some further FM updates (see: http://hg.kewl.org/s2-mfe-fm/)
I can now reliably and consitently receive DVB-S/S2, DVB-T, analogue TV
and FM radio on the HVR-4000. DVB-T works on the AVERMEDIA as per

Applications which have been under test by include the command
line dvb-utils, dvbtraffic, dvbsnoop, GUI apps kaffeine and
mythtv. No obvious side effects have been witnessed of using
MFE and the applications themselves do not see any difference
except that they are unable to simultaneously open multiple
frontends due to the hardware limitation of such cards.

A couple of problems exist which may be present in all hybrid cards
is that you are able to concurrently open analogue and DVB-T where
these share the same tuner section. Another issue with shared
tuners is where both analogue and digital sections share a sleep
method which in some circumstances is incompatible.

At this time I am happy with the performance of this MFE card
(HVR-4000) and to be honest, I am looking at attending to other
activities. Bugs where present ought to be picked up by others,
I have done all that has been reasonable to test and determine
that MFE works.
