First my setup: 3 TiVo premiers Windows Home Server (HP Data Vault x310) with 7 TB of storage running pyTiVo Gigabit switch Wired network connections with CAT5 cable My goal is to store all of my DVD rips and other video files in a format native to the TiVo, but still playable on a PC. The x301 WHS works great as a server, but is too light on processing power to do any transcoding or video conversion real time, thus the need for a video format native to the TiVo. Now I just rip the VOB files off of the DVD and convert to mpeg-2. However I have to older stuff that is MKV. I tried using a program called mkv2vob and it will convert directly to mpeg. However I must be doing something wrong because a file that takes 5-8 minutes to transfer from a computer to the WHS takes 3-4 hours to transfer from the WHS to the TiVo. I am deducing that pyTiVo is having to do a conversion and it cannot keep up real time, but I do not know how to confirm this.
