I just recently purchased an HDTV and WDTV player to be tested as digital menu boards for my restaurant chain. Immediately, I found out that there's about one second delay when the player flips from one track to another (video). Do you know, what kind of setting or divix player would not do this? WDTV is connected by the stock USB wire to WD My Book. Would using a usb flash drive... prevent this?
