I went with Tandy for the 80s because they were just as prolific in my opinion, and unlike Commodore, who only made home computers, Tandy made both home computers AND MS-DOS machines, representing the two sides of 80s computing very well. Though Commodore is still understandable given how, y'know, they made only the best-selling computer of all time, the Commodore 64.

As for the 90s, whilst I agree Compaq was a very important and influential company during the 90s, they also had some prominence in the 80s, essentially being the first truly big PC company that wasn't IBM. The other big PC company that comes to mind when I think "90s" is Gateway, or Gateway 2000, as they were known back then. They're sort of the opposite of Compaq though in that they also had prominence in the early 2000s, but declined afterwards (Gateway's peak was really the Windows 9x era, 1995-2000). Packard Bell was not only big in the 90s, but were also ONLY big in the 90s, since they didn't really become big as a company until the mid-90s, and they literally died with the decade, as they shut down US operations in 2000. I personally regard Packard Bell, Compaq, and Gateway as the trinity of 90s PC companies.

As far as the 2000s are concerned, another potential candidate, especially since I owned one of their computers back then as well, would be eMachines. They were essentially to the 2000s what Packard Bell was to the 90s, since they were mostly known for cheap PCs that weren't exactly the most reliable. I was never a fan of them, and since they were never as versatile as the likes of Dell in the 2000s, they wouldn't be the quintessential PC company of the 2000s, since eMachines only targeted the low-end.

Honestly the main reason I liked watching DVDs on my computer stemmed more from privacy than anything else. I generally preferred to watch DVDs on my TV due to the bigger screen, but this would entail the audio of the movie playing throughout the room, and for people walking in my room to see what I'm watching. Whereas on my computer I could just put on headphones so that nobody knows what I'm watching.
Another reason I liked watching DVDs on my computer was because they often came with bonus features exclusive to computers. There was a DVD player program called InterActual Player in the early-mid 00s that lots of DVDs from back then came with.
And of course, you could rip DVDs from your computer, and at that point, you could just click on the MP4 of your movie, and watch it immediately. You could even edit the MP4s and create AMVs or YouTube Poops or memes or what have you.
