The PC is a bundle and the OEM (not VLC) needs to pay for the license. I think the second case is also a bundle: there are specific clauses to close such loopholes.
Worth noting that the license is less than a dollar per device and the manufacturer is only required to pay if he sells like 100k devices per year.
The problem is that "bundling with hardware" is very vague. For example, if some OEM sells their PCs/laptops with preinstalled GNU/Linux (containing VLC), does this count as bundling. Or let us consider, say, a singleboard computer that can be both used as a PC and a set-top box just by installing a different firmware (think GNU/Linux distribution) that is provided for free (as beer) at the vendor's website - what is bundling then?
