I know this thread is kinda questionable, but here goes. Mods put it where it sould go.

I have a RioVolt PCX100. I would like to play Ogg Vorbis music on it. Can it be done? Has anyone pulled it off? How?

I am especially interested in hearing about a Firmware update that includes Ogg Vorbis. However, I guess it also can be done maybe by including a patch file on the CD in some cases. Since this device has no physical connection to the computer, the only pheasible way to possibly get patches in is by burning a CD. I do not want to modify the unit.

Unfortunately I don't believe anyone has pulled off such a hack
The RioVolt is firmware upgradable so it is probably possible.
The best course of action is to send a letter off to the
manufacturer asking them to include support.

I knew the firmware was upgradeable. I was actually asking if anyone has made a firmware crack for it. You, of course, said that it hasn't happened yet. I guess it's only a matter of time before someone pulls it off. All you gotta do is burn a single file to CD and then try to play it in there.

I've had a RIO Volt 100 for a few years and now have an iRiver IMP-550 on order. The 450 and 550 supposedly will get upgraded firmware to support OGG at some point, doubtful the older players will. I think it's supposed to be quite a bit more CPU intensive than MP3.

Hmm... Didn't realize that...

New MP3 players should support Ogg Vorbis since it's starting to become common and is royalty free.
