Summary0000491: 1) HDV format not auto-detected correctly and 2) HDV formats not available among presets
Description1) HDV format not auto-detected correctly
As discussed already in a forum thread, after reading in a HDV_1080i50.m2t file in CGG
the Set Format window seems to not read in correct parameters from FFmpeg as follows:

W.Ratio=1.0 and H.Ratio=1.0 should correspond to FFplay SAR (Pixel ratio) 4 : 3
Aspect Ratio 4,0 : 3,0 should correspond to FFplay DAR (Display ratio)=16.0 : 9.0

Not interlaced should correspond to Mediainfo Interlaced for the HDV 1080i50 ?

2) HDV formats not available among presets
As shown on Fig 3.1 in the CGG manual, the Presets defines Analog, SD (DV) and som full HD format (1920x1080) formats, but HDV formats are missing. I suggest to add the following HDV standard formats according to:

HDV 720p/60, 720p/30, 720p/24, 720p/50, 720p/25 (1280 × 720):

HDV 1080i/30, 1080i/25, 1080p/30, 1080p/24, 1080p/25 (1440 × 1080)

Steps To ReproduceAs described above

I guess when you say HDV 1080i/30 or 1080p/30
you mean more precisely 29.97 fps.

and for 1080p/24
it's more like 23.98 fps.

Wikipedia's specification of the HDV 1080i format seems to be incomplete or faulty, because the Sony HDR-FX7E camcorder specify its format to 1080/50i.
