BBC1 - Doctor Who (22 may 2010)
Capped with dvbviewer - Stream is DVB SD - TS Stream
Analyzed with GSpot and others.
GSpot Report
SAR 1.250 (5:4)
PAR 1.422 (~10:7)
DAR 1.778 (16:9)
SAR x PAR = 1.7775
----
Load file into virtual dub (vdub) it shows on screen as 5:4 (the file info says its 16:9).
Add a video filter and select VDMod_Resize it also shows as 5:4.
If i set that to 16:9 then 720x576 becomes 720x405
If set to 1024x576 (16:9)
Or
If set to 512X576 (16:9)
Both of the above output 16:9 but the pixel shape is incorrect. The picture is wrong and more telling on gate sign at 08:03s into the program. It shows with near double lettering or near ghosting. Obviously its not jst about the gate sign lettering as the whole picture is affected, not clear and sharp as normal 16:9 would be.
Is there a way to correct this without having to resort to letter box black bars at top and bottom to make true 16:9. When viewed on pc at broadcast it was shown in full 16:9 without the black bars. Dvbviewer set to shown picture as broadcast, with no picture transform etc.
