I have a Pioneer DV-410V DVD player with a USB slot. It is hooked up to my LCD TV with an HDMI cable. So, I can use a memory stick to play AVI files, WMV files and several other formats through the USB port. But when I try to play a high definition file using the USB port, I get a message saying "resolution of this file not supported," even though both my DVD player and my TV support a wide range of resolutions. Has anyone encountered this problem?
