I've had a Muse dv-310 for a while now and it's been great. Tonight I'd tried playing some Divx file that should have worked but there was a problem. So, I thought I'd check for a firmware update. I google Muse dv-310, nothing, I try a few combinations of Muse, DVD, 310 etc. No luck, I can't find the model of manufacturer anywhere. I bought it from a clothing company on EBay so I don't expect them to be any help, but I emailed them to see if I can track down whoever made it.

Does anyone have any bright ideas on how to help?

Edit: Musestyle is on the ODS background but the place I bought it called it Muse, either way still no luck.
