why setle for 60Hz/200Hz.. Panny plasma is already 600Hz..

600Hz is not the actual refresh rates of the panel. It is the sub pixel drive.

Plasma refreshes totally different from an LCD panel as such the motion response on a plasma is better.

Ask them to play astro for u and if u r happy with the quality at the distance that u plan to watch it at, it shd be ok.

Sammy processing is pretty good, so make sure u take ur own dvds and check to ensure that u r happy.

Things to note about LCDs/LED backlit LCDs, if u watch in the dark, black levels are not that great. However, the LED backlits are typically better than CCFL LCDs. Also look for clouding and see if it effects u. Another point to check to see if u can tolerate is SD (Astro) sports channels.

Each display technology has its faults, if u can live with them, then u're good to go.

check your thumbdrive... see the FORMAT is it in NTFS or FAT 32/64

if still happen try FAT32 should be OK the older LCD/LED/HTIB usb only support FAT32

TV usb drive koyak... (did you test another tumbdrive)

see setting in TV if it is disable... (i doubt so)
