I'm now having similar problems, smb worked somewhat (laggy on full length vids, but ok for 30 min episodes) back in early part of November on my Linux file server/router. Since the improvements that work for some people, I haven't been able to access anything on smb, either on linux box nor on the vista desktop, just detects wii IP and then returns to top of menu.
Here is sample from mplayerwii.conf file.
the two entries for tv/ and Sarah Jane have not been modified, neither have the files themselves, simply updated the DOL, have also tried ti compile from source both trunk and gui branch
#linux
