What I want out of a video player is the ability to render subtitles at native resolution when a video is full screen, so the text isn't pixelated because it has been rendered at resolution of the video when watching SD content. The only player I have found that does this is XBMC which really isn't really ideal for the kind of things I use VLC for. I just checked out MPlayerX, and it sadly does not fit the bill. Do such programs exist?
Unfortunately, I think your best bet is to install Windows via Bootcamp and use Media Player Classic Home Theater. It has an option to force subtitle rendering at a specific resolution.
I don't know of anything else on Mac that can do such a thing. I have heard that Plex might be able to do it, but I haven't checked that one out yet.
I guess what I was asking was does the Macbook Air have better screen display quality and better video rendering quality as well compare to Non-Apple products such as Samsung 9-series?
From my experience, the screen on the Macbook Air is a hit or miss, really. For some reason, Apple's display quality got worse with the Macbook Air and iPad 2, and the difference in quality usually comes down to whoever manufactured the screen. If it's a screen by Samsung, then most of the time, it's acceptable. If it's a screen by LG, then I'm not sure if you'll like it, because most MBA owners I know of loathe having LG screens, and they would exchange their Air's multiple times until they get a Samsung screen.
There are multiple threads over at MacRumors forums dealing with this issue...
And by the way, I mentioned "acceptable", because to me, a Macbook Pro's screen is still far more vibrant and better-looking than the Air's. I have and Air with a Samsung screen, and the colors look far worse than a Macbook Pro's. I think you can see the difference quite clearly if you go to the Apple Store and play with them side by side.
Compared to another device, I honestly have no idea. I haven't touched Windows laptops in a while, but if reviews are to be believed, I think the Samsung Series 9 is quite a serious contender where screen quality is concerned. Other devices don't seem to be comparable to the Air's, even though from my standards, the Air is just about acceptable with a Samsung screen.
Not necessarily, that is a software function as much as a hardware one. I can say this much. My 1.4GHz Air (Oct '10 model) with a 320m can playback 1080p video with nary a hiccup. Not so great with netflix streaming lately, not sure what is up there, silverlight must be bugged, but other than that...
Silverlight doesn't have GPU acceleration, and most of the processing is done on the CPU as far as I know. Netflix seems to have boosted its DRM measures or changed the video format, or something, and as a result, I find that many of my devices that could barely play Netflix SD before now almost completely unusable with Netflix. And unfortunately, Microsoft is still mum about h.264 or GPU acceleration with Silverlight. Last I heard, they may drop it altogether.
Honestly, I don't think it's that hard for Netflix to come out with a native app on Mac and Windows. I think we should all boycott them for it...
