mpeg2video / wtv resolution regression

[cehoyos]

User blade005 reported a regression on the Zeranoe forum. Attached wtv sample is detected with a wrong resolution of 704x480 instead of 1920x1080 since 4dee4a44 - possibly related to ticket #3912 (which was fixed in the following commit).

$ ffmpeg -i 1920x1080_cut.wtv -f null -vframes 1 -map_metadata -1 -
