The Asian CNET has a preivew on LG's upcoming JM52:

The 1.7-inch screen on the JM52 is large enough without making video viewing an eye-strain on short trips. We loaded video clips of varying formats (AVI, WMV, DivX, MPEG-4). However, it seems our test unit supports only the MPEG-4 format for which we are fairly sure the retail unit will ship with some form of video converter software..
