Just a 10.04/.23 status update. I've configured X and mythfrontend on my xubuntu 10.04 atv install. Bootup memory usage is under 230MB, with no swap being used. I have not tried playing any videos or recorded shows yet.
This is a bit more memory usage than I had with 9.04 and myth .21, that combo used just under 200MB after bootup. I have not seen if the new mythui can be made slimmer yet.
