Lately some of the videos I upload to my Tivo won't play. I get a message to the effect that the copywrite holder won't allow it (or some such).
These videos easily play on my PC using VLC media player.
So why doesn't Tivo like them?
These seem to generally be .MKV files but other .MKV files play fine.
I'm using PyTivo to transfer the videos from my PC to Tivo.
