I've had this mp4 player for about a year and a half, so I can't contact the seller or view the ebay information.
The mp4 player came with a sample video, however I deleted it a year back.
I figured out that the format is AVI after converting all types of MP4, AMC, etc.. for two hours.
The AVI videos are listed, but it reads "format error." I formatted it and it turns out to be only 4gb.
The MP4 player has a 1.5+ Inch screen,
It looks like an ipod chromatic,
The firmware reads: 20090206, V1.2.3A, DVTVB1, 20081212.
It doesn't work with the MP3 disk tool, so I wonder what the chip is.
I have been frustrated with this $20 piece of equipment for hours.
Thank you!
