i recently went out and brought a new HDTV..LG scarlett 2.0 which is FULL HD. it has a inbuilt DIVX USB port which can play audio and video. I am new to the HD file conversion thing as i usually download MKV files which obviously wont run through the USB port. i want to know what are the specification and limitations of this usb port??? so i downloaded a HD episode(Entourage) which incidently turned out to be MKV. after conversion at the similar bit rate and aspect ratio and resolution i got the .avi file. so i connect my USB and try to run this file which is a 720p file. but the it wouldnt play the file and quotes a "invalid file!!" but it is playin a piped version of the same episode(.avi) at 624 x 352 resolution. im confused here if i can play a 720p file using an USB or do i need HDMI and a upscaler?? please help me out with it..
