If you're wondering, 576p is the 16:9 ratio that the iPad is capable of (1024x576). It's not really HD, but it's significantly better than DVD (58% higher res.). I like Air Video, and it works wonderfully on my iPhones, and even on the iPad for SD content, but on occasion I want to stream HD content (720p MKVs) and I can really tell the difference. I know my network (G/N) can handle the bandwidth with ease, and I'd guess my Mac Pro can handle the 'on the fly' conversion. I was mid-way through watching a 720p rip of the NBA finals and needed to be elsewhere in the house to supervise my kids, so I decided to just stream it with Air Video. It was watchable, but it seems very choppy/blurry, as in basketball a lot of the screen information is changing with great regularity and it's constantly zooming/panning. I'm sure converting a file to 720p and copying it over would yield better results, playing natively, but I'm hopeful for some other option. I know Air Video kindly made their app 'universal' so it plays on big and small iP* devices, but I do wish the iPad had better resolution support. Any idea if that's coming?
