No idea. I don't use TD. pyTivo reports the size of "Mimi wo sumaseba" as 13.4GB. I just started a transfer to my THD. The length in the info for the entry in the NPL is 14.08GB. edit: I'll report back when the xfer completes. Ir's gonna be a while. edit2: Transfer complete. Reported size is 5.56GB. Sort of irrelevant. The TiVo has to create enough free space to hold the calculated maximum. There might be an entry in "Recording History".
