Ok, this all came up in the "MBA as the only laptop" thread, but as to not hijack that, I thought I would repost a new topic. Basically, I had a 2010 13" MBA 1.86 C2D with 4 GB of ram. I bought it to replace my 2007 iMac (with slightly higher specs) and iPad combo. After getting used to the size difference, I was quite pleased with my choice. Until I ran into a video output problem. Basically, it couldn't output through Mini Displayport to HDMI to HDTV at 1080p and had similar, but slightly less issues while trying to output 720p files. Most of the time, the video would stutter. Sometimes it would blink in and out and sometimes it would act as if it was playing in double the speed (while the audio stayed at regular speed). I mainly used VLC player as well as Plex with similar results from both. I inquired here and a couple other places about it, and the consensus seemed to be that it was because I was running the video and audio out through the MDP and that it was too intensive to transcode both? The suggested route was to run the audio out from the headphone jack. Which is what I used to do with the iMac (optical out to receiver and mini dvi to hdmi/tv). But the MBA does not support, as far as I know, mini optical out. Which would kind of defeat the purpose of watching HD video with standard stereo sound, no? So, my questions are... was I doing something wrong? My 2007 iMac had no problem whatsoever pushing that type of video out as well as multitasking while doing so. I don't see why a 3 year later machine of similar specs could not do it. What are the chances of the new Sandy Bridge MBA's being able to do this with no problem? I have since went back to my iMac/iPad combo, but I would love to give the Air another shot if it can do this one, but fairly deal-breaking task.
