Earbanean: We currently solve this issue (when we need to), through our Sony blu-ray player, which sits next to the ATV. For $120'ish it gives us the only (and last?) physical disc player we'll need (plays blu-ray, DVD, CD and even SACD), supports all the streaming options (Netflix, Amazon etc), has DLNA for home server stuff, works wired or WiFi etc. Only downside is the interface for Netflix etc not as nice as the ATV, which is why we prefer the ATV for the services that it supports.
Earbanean, how did you get Netflix on your Sony Blu-Ray player? Mine doesnt show the app at all. Ive tried linking it to a US Sony Account but still no app.
