I'd like to see Gog use something besides Youtube for the store page videos. I find Youtube a bloated mess with lots of javacript and high CPU usage. I feel if you're downloading an advert for a product you should be able to watch it in the program of your choice or save it for later. This used to be possible in Youtube when it first moved to HTML5 but they've since moved to their own player which limits what the user can do. I don't know if advertising is a factor (adblock plus is awesome and I don't see any) but you may also be seeing adverts when you watch with Youtube.

It is possible to use keepvid.com to avoid running scripts but this is longwinded and shouldn't be required.

The bottom line is this: I'm not watching game trailers here. Maybe you're not or maybe you feel it's less than optimal. If videos were hosted with something like MediaDrop, it could be a lot more useful.

An great example of mediadrop is the rather awesome OpenStreamer.org.
They host lots of videos of game playthroughs. The site works without javascript and videos can be downloaded.

I invite any suggestions/discussion on what would make the hosting of videos better. Thanks for reading.

Youtube makes is more easy and practical for GOG, or any other site for that matter.

It is a ubiquitous thing at this point, THERE IS NOTHING WE CAN DO, NOWHERE TO RUN, GAME OVER MAN!

Unless GOG grows, and I mean reeeeeaaaalllly grows, to the point of when hosting their own videos somewhere becomes better than hosting on YT, I predict no changes in the horizon.

Advertising on the videos themselves depends on the channel hosting the videos and how they set each video's advertising options, for one. If you wish to see the game trailers on GOG here, you will not see advertisements.

nice try, keepvid.com employee

either way, gameplay video from lets plays is always going to be superior to game trailers.

Not to sound offensive, but why would the average user care about this?

It's pretty much as neurasthenya said, it's not going to change anytime soon until GOG grows substantially. They have no reason to change it for the time being, and even if they did, they probably couldn't be bothered anyways.

In addition, we don't want whatever nice implementations GOG has for streaming videos to us. It just so happens that YouTube is great, tested and tried in that field, so everyone uses it. Now if GOG uses their own implementation, let's just say the results may be less than stellar.

Nah. The average everyday user doesn't care. That is the point why GOG has no reason to change.
It is more practical to use what is cheap and ubiquitous than make a expensive change because one user decided that it isn't up to his standards. Humour up a bit sunshine, I'm jesting. Also I'm quite surprised (and glad) that GOG still on business.

I actually do find that kind of weird, yes. Why would somebody care about this when it's a game trailer? Typically you're watching the trailer while online and looking at the product.
I mean, it's fine if you want it, but it feels like an insanely niche thing to expect them to implement. But please take into account the fact that I'm completely tech-illiterate and thus completely unknowledgable of the finer details of how this works/its benefits.

At least here in China they already do that. In June they switched from Youtube (which is blocked here) to Wistia Player which is now embedded in the gallery instead of Youtube,.

Like others sounds like some want to push their own product. GOG uses youtube cause its convenient AND much of their customer base are likely to use youtube by default anyway (name other similar sites which has such ease of access and plentiful content...)

All the trailers GOG uses for their product pages are versions edited by & for GOG (meaning "having had the GOG logo added to the end"), and they're hosted on GOG's own YouTube channel. Nevertheless, in the past, I've occasionally gotten some ads when watching them (which is ridiculous when one considers that the trailers are ads themselves, being used to sell things on GOG).
I haven't noticed this in a while, but it's hard to say if that's because GOG's gotten big enough where they can push back against YouTube's content ID system imposing ads on videos because someone made a claim against them, or because I seldom watch trailers, and have gotten lucky with the few I have watched in recent months. ;)

I don't watch any of the GOG's trailers embedded here.
Occasionaly I watch them when I am browsing through YouTube.
For me these trailers barely carry any weight to influence my judgement. I prefer to depend on reviews and let's plays.

I would prefer self-hosted videos that are embedded normally for the browser to play, but there are practical reasons for GOG to use Youtube instead. It eliminates GOG's video hosting burden entirely and racks up Youtube views, which increases the chance of people stumbling upon the video outside GOG's website and maybe attracting a few new customers.
