Just thought I'd post an update with the results of the changes I made to get mfs_ftp working. I changed the FlashFXP settings from passive to active, and capped the download rate to 800k/s - figured i'd rather have the client dictate the download speed rather than have the transfer saturate the tivo's cpu. It's worked flawlessly since. While it'd be nice to have the transfers a bit quicker, it's just a matter of queuing up the files and leaving it to do it's thing.
