For your Topic Question.. There's no HDMI port for External Casing HDD and
Second... When plugging USB devices and Playing directly from TV, you will not have any problems and yes of course the quality will be good But the Colors will not be upto the mark compared to When Playing through Blu-Ray Players or through PC HDMI or DVI (Ofcourse with little enhancements ) .With PC, in Players enabling Shaders will bring your movies more Colorful but still with good Natural Colors.
Example... If you use TotalMediaTheater or PowerDVD, especially TotalmediaTheater brings Movies into life than through TV USB's. It brings awesome Black Levels and Contrast which looks 2x times better than playing directly from TV USB's. Sometimes not all the Blu-Ray MoVies will have reasonable Noise. Especially Recently released MoVie "The Awakening" does have very Bad Noise Pixels and With PowerDVD options such as Noise Reduction you can Bring Decent Quality. Also through Media PLayer Classic you can enable Shaders especially 16-235 -> 0-255 [SD][HD] and see the Black Level Difference on and off. With Simple Shortcut you can on and off while playing Movie. Similarly you can add more shaders and bring your Old Videos to life.....
These are the main advantages you can get playing through PC than compared to USB plugging... It's not that through USB you will Loose Quality.. But Once you are used to these Players and watching through USB is like "you can't watch it anymore".
Also get the most of the Quality from High End HDTV's is what I am saying overall.
This feedBack is coming from the Guy who Watched Lots, lots of MoVees through PC and USB in HD Displays...
Rest it's all on you to Choose depending on the usage and Flexibility suits you.......
How can I check these technical details in the rips? Any suggestions?
I opted for Samsung TV over Sony since Samsung could play more formats compared to Sony hence save me from investing on a Media player atleast for sometime.
But looks like I would still need a HDD Media player.
You can still Play all the Formats without HDD Media Player through your TV. When you are not using External Home Theater you don't have to worry about Sound Channels Becoz with TV Crap speakers you can't expect them to sound Awesome.
