No hurry, will wait for whatever receiver comes out with some worthwhile bells and whistles in the next few months. Since mkv files are smaller than mpg2/4/avi, but still have great video quality, makes sense to use that format if downloading via internet.

Just read that the A3 has 2160p resolution available in the Euro vs. the old NA version. So, if time permits, will most likely convert to the Euro version and test.
