bicubic 2(4,8..)x + sharpen + downscale to screen could look very nice.

Maybe there could be an option to turn it off/on in an upcoming release? Good work, as always /Martin @elan

Just because I'm usually drinking at the time doesn't mean that it's the booze talking. Of course, I'm enjoying a Bloody Mary at the moment, so you know what that means. @nefilim: It's possible, there is a bicubic upscaling implementation in there, but it doesn't seem to work on my desktop NVidia card, and it's unknown whether it will work on GMA950/X3100.

The alure of XBMC, for me at least, had always been its ability to scale a relatively low resolution (SD) image to HD, and make it look good. Yes, the interface is really slick, yes, there's nothing like it out there, but ultimately it's all about the quality of the image. I don't know how many times I would have people over watching a movie, then they would comment on how clear the video was, and I would, just for kicks, cycle through the resolutions 'till I got to the original size, and their jaw would drop when they would see how small the original image was and how good it looked enlarged. Getting bicubic scaling going, and whatever other tricks the old XBOX/XBMC was capable of that made the scaling look so good, is ultimately what we're all looking forward to. Yes, HD content looks great already, but not everything I have (or most of us have), is HD content, so the abiltiy to make SD content look realy good is a major plus. I don't want to have an Xbox to play SD content AND a Mac to play HD content. One box should do it all. At the moment I'm still using my old Xbox connected to the HDTV, and XBMX Mac on my 24" iMac, but I can see that soon I'll be retiring the old box in favor of a shiny new Mac-Mini. Keep up the great work, and thanks again for your efforts. This is getting better and better…

Any chance of doing this in hardware with OpenGL? On a vaguely related note, I recently did a quick comparison between the H264 output of VLC,MPlayer and threw in XBMC-OSX at the end: http://nefilim.wordpress.com/2008/03/15/h264-quality-differences-in-players/ Pretty cool!

If it works as an excuse when you do something illegal, it will work everywhere... Atleast where I live :) I think you have a fault proof concept there when you always as a last exit blame the alcohol for whatever could be wrong with your ideas.
