NWZ E-345 Pix & Vid Issue

[shutterbug98]

I've had TWO new players in the last three days. They load & play my music files just fine, but it refuses to list or play my properly formatted pix or video files. The only ones that WILL play are the samples that came preloaded on the player. My files load & play JUST FINE on my old Sony Walkman 4GB .mp3/.mp4 player. Sony Tech Support was of NO help...the suggestions they offered to fix the problem, I had already thought of & tried, to no avail. You would think that SOMEONE on the planet would have had this problem with the NWZ E-345 & Sony would have an EXACT solution. Other than the problems I'm having with the pictures/movie files,I REALLY like this player & I WISH I didn't have to return it, but I CAN'T afford to eat $75. Has anyone on here either had or heard of this? What can I do to fix it?
