- does eHD support 1080p ?
Nope. Max is 1080i@60Hz. And for normal viewing, 1080P is still a thing in the very long future (for your information, we just got HDTV since March) and it would be only be interesting for the HDDVD and BluRay movies.
what's happen if you will try to play 1080p mkv/bluray/hddvd files on your vdr with eHD ?
