IIRC, the N810 just can't handle playing a typical DivX (e.g. approx 350MB per 40minutes TV episode) from a network share folder via Wifi all that well (in terms of battery life). I believe your 8-hour playback time is from local SD card with a re-encoded video (one that's specifically for N810's resolution and bitrate), right? And yes, here in Hong Kong...people are always in a rush...in the fast lane. You're not?
