>>>>>>>>> I have done a quick, first

>>>>>>>>> camera. This is a HDV 1080i
>>>>>>>>> camcorder with MPEG-2 video
>>>>>>>>> compression at 25 mbps on tape
>>>>>>>>> 1440x1080, 50i25fps, 4:2:0 and
>>>>>>>>> MP2 stereo audio. Currently

>>>>>>>>> and needs repair service.
>>>>>>>>>
>>>>>>>>> But according to Steve
>>>>>>>>> Mullen's V1 and FX7 handbook
>>>>>>>>> (not mentioned in the manual):
>>>>>>>>>
>>>>>>>>> 1. When the camera is
>>>>>>>>> operating, the EIP
>>>>>>>>> (Enhanced Image Processor)
>>>>>>>>> generates uncompressed
>>>>>>>>> 1440x1080i with a 4:2:2
>>>>>>>>> color space. Digital 4:2:2
>>>>>>>>> data are output via the
>>>>>>>>> HDMI port while 4:2:2
>>>>>>>>> analog is output via
>>>>>>>>> component-out. Therefore,
>>>>>>>>> you can record 4:2:2 live
>>>>>>>>> HD video from the camera
>>>>>>>>> without MPEG-2
>>>>>>>>> compression. V1 and FX7
>>>>>>>>> provide an HDMI output
>>>>>>>>> port that carries
>>>>>>>>> uncompressed 4:2:2, 8-bit,
>>>>>>>>> digital video plus
>>>>>>>>> dual-channel, PCM, 16-bit,
>>>>>>>>> 48kHz audio When the
>>>>>>>>> camera is running.
>>>>>>>>>
>>>>>>>>> 2. If you are playing a
>>>>>>>>> 1080i50 or 1080i60 HDV
>>>>>>>>> tape. The 4:2:0 MPEG-2 is
>>>>>>>>> decoded and chroma
>>>>>>>>> up-scaled to a 4:2:2. The HDMI
>>>>>>>>> chip downscales 1440 to
>>>>>>>>> 1280 while it up-scales
>>>>>>>>> 540 to 720. The result is
>>>>>>>>> 720p50 or 720p60, which is
>>>>>>>>> output via HDMI.
>>>>>>>>>
>>>>>>>>> That is, I have tested section
>>>>>>>>> 1 now, but see now that I
>>>>>>>>> didn't test 1440x1080
>>>>>>>>> resolution. The only
>>>>>>>>> resolution I got to work at 25
>>>>>>>>> fps was 720x576 (SD), while HD
>>>>>>>>> 1280x720 and FHD 1920x1080
>>>>>>>>> were set down to 10 fps and 5

Trial_3_ with ALSA Audio input instead finally playbacks the audio !
As seen from mediainfo output below, the FFV1 1920x1080 video stream
with 5 fps makes up 94%, the PCM audio 3%
In comparision the FFV! 720x576 video stream where the Hama ms2109
capture manages 25 fps, the sizes are 95% and 3%
