Ok i got a few:
1. I tried to backup a DVD (original movie) just for the sake of tryin and it freezes (tried a good 5 or 6 times)
2. Every now and then, not that often, when i boot up my box and hit the thumbstick for shoutcast my box freezes. (i don't have ne of the /stream####/ sites because i realized this does not work... when i entered the site into my IE it said that winamp is required to play)
3. Shoutcast problems (not sure if this is ava or the server) stations will play way to fast/slow or play,stop,play,stop. gets real annoying but if u just hit the thumbstick again u might find one that doesn't do it.
4. UNSTABLE freezes a lot! no particular reasons.
That said i LOVE avalaunch compared to other dashs, someone in #evolutionx suggested using it (LOL) a few days ago and i've been hooked!
