[QUOTE="RonD, post: 1047648, member: 117536"] For my flip tests I used the same pair of channels for ATSC TV and MePo, KPIX 5.1 physical=29 and KNTV 11.1 physical=12. On the ATSC TV flipping between 2 ATSC sub-channels on the same physical channel, 11.1/11.2 or 7.1/7.2 seems to take about the same time as flipping between different ATSC 7.1 and 11.1 channels. On MePo the same sub-channel flip is faster. The ATSC TV is still a bit faster but not a full 2 seconds. Its hard to get a real apples/apples comparison. The main ATSC channel 5.1, 7.1, 11.1 is a higher bandwidth HDTV video, the sub-channels are always lower bandwidth but not sure if that makes a difference. Another comment, if I watch MePo on a LCD Monitor and live ATSC TV that are next to each other, the MePo video/audio is about 0.5-1.0 sec delayed compared to the ATSC TV. I guess MePo has some amount of buffering between the receiving the channel and displaying the video. [/QUOTE]
