Default Re: Video Memory needed for 720p / 1080i?

My Mini has the default 1GB of RAM, meaning it has 256MB of video memory. Is this a factor?

Are there any other tips for people using the nvidia-based Mini? I'm guessing this is a very common HTPC platform.
As far as I'm aware, having 1GB of RAM, only gives you 128MB of video memory, which may not be enough.
To get 256MB of shared video RAM, you must put 2GB of RAM.

You say you get an error in the log, which one is it ?
