this automatically.

Downloaded video play fine. Im just worry about "malformated aac bitstream. Install ffmpeg or avconv to fix this automatically". Is this not a big deal? Also im not sure that i download in maximum possible quality. Do i use right command for it? Can someone tell me is 7.45 gb is a size of maximum quality version of this VOD? Thanks.

malformated aac bitstream

Some old or crappy video players can't handle such streams. If you can play it fine, that's OK.

maximum possible quality

Yep that's the default.
