I have done this many times with mp3's. I think I have also done this with avi's. And, I have never seen a failure. Since you can read directly from the windows drive, so there's no need to use the pen drive in that direction. I would suggest a test. Copy the files on the pen drive back to your linux side and try to play them then. My first thought on reading what you wrote is a faulty pen drive, because I can see no reason why it wouldn't work.
I'm assuming that the pen drive is formated in FAT32?
Also, I think by default NTFS write is disabled in the kernel. So, even if you give the write option, you would not be able to. You can recompile your kernel to fix this. But, last I looked, NTFS write was not reliable.
Sorry if this isn't helpful.
