If you're talking about the device that this forum is about (The WDTV Live / WDTV Live +)
The ONLY loss of function I'm aware of is that the RESUME function for DVDs will not work.
If you're talking about the WDTV Live Streaming Media Player that was INTRODUCED in 2011, then there's LOTS that won't work if it doesn't have write access, and you're in the wrong forum.
