I've never done this before...so for me it's a big deal.
Intrigued by all this business about backing up my shiny discs...and watching via the BDP-93
Downloded mkvmaker..ripped a DVD bit for bit,,, copied it to portable HDD...and watched form HDD via eSATA port on BDP-93.
Unfortunately it's a DVD I've never previpously seem but ion the main it looked good to very good.
Sound was DD although started as stereo and when I played around (with AVR) lost the soud. Restarted movie and it's all in DD and no dramas. Plenty of pausing and rewinding and turning on/off subtitles and it was perfect all the way through.
Movie was The Men Who Stare At Goats - which my wife hates but me and the 14 yo quite enjoyed
