You can use HandBrake to do the job. Here is a very good guide to convert videos to h.264 for Archos 605 using HandBrake. HandBrake is Open Source, costs nothing.

@CheBuzz: What I really wonder is why there isn't already something for gen5 devices from the community. There is no need to be a full operational system to substitute avos, but just a possibility to load something other.

After Archos, have the open developement guys here forgotten the Gen5 devices?
It would be nice to have a chance to install some other os in it.

Wonderful work! haha
Sideways, is it possible to create a program to direct search and stream videos from sites like youtube? Something like the program minitube for linux but not limited only to youtube?

Needing some cheese here too. Thanks in advance.

Is there a way to use the GTF3 approach to replace the "libflashplayer.so" (the old dated adobe flash player plugin from opera mobile) with a new version? Maybe we can use a version compiled for a mobile phone like the ones from nokia. Someone knows if this is possible? Any information? I'...

Can I repack a plugin with this utility?
