I purchased a new LT-H90LAN last week and it is connected to my home network via ethernet. I have several videos in mpeg-4 and mpeg-2 formats stored on a Buffalo Linkstation Live LS-CH1.0TL. Several times during playback of different clips I notice my HDTV screen goes blank for 1-2 secs as if the wired connection was momentarily lost. Interestingly, when I rewind these videos the glitch seems to occur at the same spot. Also, the order of video playback sometimes is incorrect with later scenes played first out of order. I recode/transcode videos using Nero 9 to make AVC video. The Firmware on LT-H90LAN is the latest (after initial installation the firmware updated automatically over internet). This problem seems to occur 99% times with AVC(H.264) videos. I don't have any VOB files.
