"MHz", you mean. ;)

It's partly the processor bump and partly Flash improvements. For whatever it's worth, Diablo's Flash seems a little bit better than Chinook's.

Wow I cannot believe I just did that. I've been working with computers since I was like ten. Running on five hours of sleep is definitely not good for me :P

hmmm I kinda wanna upgrade to Diablo but every time I approach it I decide to wait for the official release

I am having great luck utilizing PocketDivXEncoder on my n800 with MPlayer - settings I used are 320x240 with audio and video turned up to max (Produces a 320x240 @ ~24fps DX50 and 96kb/s Audio). It plays perfectly, and scales quite pleasantly up. In general, I am more pleased with the video playback on the n800 than I am on my PSP, although that could be that I didn't want to spend the time recoding everything to MP4, which took nearly real time versus about 10x real time in PocketDivXEncoder...

I don't understand Arnim-- I stated that the video codec/format situation could only get better (I don't expect it to get worse). Why wouldn't that be true?

Come on, you can save face; just say your shift key missed; you meant mGHz. (yep, milligigaHertz!)

I bundled this into a shell script that attempts to auto-determine the best settings and calls mplayer with those settings for optomized or unoptomized content.

Mopt.tar

download, then untar and chmod with
tar -xzvPf Mopt.tar
cd /usr/bin/
chmod +x mplayer-opt

you can then invoke it on any movie file that mplayer supports by typing
mplayer-opt <filename>

That's magnificent, you guys. I think you should work with Serge and the mplayer team to get that built-in to the next release of the tablet's mplayer, whether it is through the gui or made into a commandline option (something like "--tabletrecode"). This should be available to the masses, transparently.

By the way, I can convert DVD resolution widescreen movies to play beautifully (people usually gasp and stare transfixed) on the N800. The N800's screen is really a joy to behold. The secret is using all of the screen's real-estate.

You have to resize the video to 240 pixels vertically, and then crop horizontally to 400 pixels. Yes, this involves cropping some video from the sides, but the results are far more impressive than leaving it letterboxed. I found bitrate is very important, too. I found that a high-action TV episode plays beautifully at 550 kbps, but at 650 it stutters at the exciting bits.

Transcode some cool high-action video to 2-pass XviD 400x240 at 550 kbps, and then show it to your friends. Lots of "ooohs" and "ahhhs" will follow.

EDIT: I also recommend breaking up long movies into 30-minute or 1 hour chunks. Searching is a real pain if you lose your spot in a 2 hour movie.

EDIT2: I just checked my copy of Ratatouille, and it plays back very nicely at ~700 kbps. So YMMV. Maybe there's some interaction with the audio encoding, which can vary dramatically from video to video.
