I happen to live there. It can also record normal cable TV. And, "nope" to

Hmmm, must be the mostly-emulated FPU...
But anyways, PC Intern about the ECS i-Note IN22 (VIA C3 GigaPro):
"Trotzdem meisterte der i-Note auch Multimediaaufgaben wie das Abspielen
von Filmen oder Musik ohne problemen"
In English: "The I-Note even does multimedia-playback like video or music
quite nicely". Though that doesn't say anything about DivX in special...
They ran it on Win2k.

Athlon XP 1800+ : 89.00
256MB DDR333-CL3 : 85.00
Adds to 174 EUR, pretty sloppy motherboard for ~40 euros. Cheapest ('good'
one) I see are ~85 EUR. btw, 10 EUR more and you have faster DDR266-CL2.
And off coarse SDRAM is about half the price per MB.
No offence meant, but $50 for a case would probably buy you one you _need_
to put in a closet, I guess. In my case ;) a desktop model won't fit (not
enough space near TV).

Someone told quite recently on the list that he experienced this.
