After learning that my nice WD NAS will not be able to support TVE I decided to try something that I didn't think would work. I installed the DVR Server app on my Mi Box S. To my surprise not only did it work, but TVE also worked. On top of that I was able to record 6 things (4 Connect Quatro, 2 TVE) while watching a recording from the Mi Box on my phone with the Mi Box connected to my network using WiFi only.
I never imagined this would work. Currently I just have a small HDD connected to the Mi Box and I ordered a USB-Ethernet adapter to make sure the wireless network does not be come a bottleneck. I'll be testing this for a while to see if it fails before putting it into full service.
Has anyone else tested this out? Have you discovered any pitfalls with using a Mi Box as the DVR server?
