Why No Metadata in ITV flv Downloads?

[Budgie]

I have started to use gfv (version 1.25 on 64 bit openSUSE 13.2 with KDE desktop) to download some ITV programmes. I intend to re-mux them with ffmpeg to .mp4 container.

As part of the process I checked an .mp4 file and found no metadata. I assumed I had lost this through an error on my part with the re-muxing process but on checking the downloaded .flv with mediainfo I cannot find any metadata.

Is this due to me making an error with gfv or an economy on the part of ITV?

Grateful for some guidance here please.
