Commented Issue: .Tivo Files, How do I convert Them? [1731]

I am using Tivo Desktop to download .Tivo files from my new Tivo Roamio DVR. I select them for convertion and have added my MAK key from the tivo. The result I get is:
Source Video -> D:\My TiVo Recordings\Blade - ''Dead on Arrival'' (Recorded Nov
17, 2013, G4HD).TiVo
Profile -> MP4 Normal
Conversion Task -> Convert Tivos
Error -> Remux failed
Failed At -> 2013-11-17T11:39:52

What is wrong? How do I convert .Tivo files?
Thanks!

Note you still need to enter the MAK key in MCEBuddy to extract the metadata from the TIVO file. (Your TIVO desktop MAK key will be used for decoding using directshow, but the MAK key in MCEBuddy is required by TdCat to extract the metadata and also fro Tivo decode incase the direcshow streams fails (as a backup))
