This is my first post and I have tried to read the whole PMP section before I posted a question that had already been answered. If I missed it, I am sorry. Here's the issue: I have several dvds and blu-ray discs that included a "digital copy" of the films for use on portable players but I can't get them to work on the PMP-140. I have tried the iRiver Media Converter and Iriverter as well as several others I've seen mentioned on this forum. The digital copies are in .wmv format or .m4v format (for ipod). I guess I could try to convert from the dvd, but then what's the point of the digital copy? And I can't convert from the blu-rays because I don't have that kind of drive on my computer. Thank you.
