what format is the site streaming? That matters...if you research mplayer you will find it's possible to use xterm (the command line in case you are new to Linux like I am) to stream the channel/program.

Some caveats...the NIT's are somewhat fussy about video. You will likely not be able to stream HD stuff w/o using a "man-in-the-middle" to re-format the content for the NIT on the fly or so you can d/l the video. I have not found anything that can receive a format and spit out a re-encoded stream on the other side on-the-fly. But you would think it has to exist...somewhere...

I have found that once I followed the suggestions from the tablet-gawds around here and re-encoded video to something the NIT's like...say 400x240 and a frame rate of about 29.xx (I forget the exact value...) I get GREAT video.

There is an app called Nokia N800 Video Converter that does a fine job and can run in batch mode on your PC. BTW, all conversion is done on a PC of some sort I am not sure of the exact apps for each OS but there are out there...

What I have been doing is ripping streams overnight then I batch convert to something the NIT likes the next night...so I sort of have a nice library I can choose from when I know I might want to use a video on the tablet...

I can say once massaged the video is AWESOME on the N800...sound is usually an issue if you want to use the internal speakers. But headphones/earbuds are great.

Mplayer Info, program & doco

Lots of folks will surely be along to fix whatever I goof'd but this is at least a place to being...

EDIT: FYI, I tried to view a couple channels on the site and Media Player tells me the format is corrupted. The site claims WMP format...but something is not kosher. I have not tried using mplayer.
