i recently purchased a yamada dvx 6100 mpeg4/dvd player its really really good plays most things im putting on cdr however, a few cd's are not playing properly this i know is due to a codec update issue i have read the manual and been on the website and have no idea on how to update the firmware on the player if anyone else knows please tell peace!
The best site to go to is setup by a fellow 6100 owner (he was so impressed with the player he setup a website!). On it you will find the latest firmware and other sodtware you may need. The address you need is:- www.my-yamada.co.uk Have fun.
