"I think the 1400 has a slightly higher bandwidth (down 3dB@60MHz) while the 5660 is down 3dB@30MHz ... one generally wants a bandwidth for the device to be ~3x the bandwidth of the signal you're pushing through it in order to avoid noticeable degradation. Regular DVD is 6.75 MHz, 480p is 13.5 MHz, while 720p & 1080i both are 36MHz ... Neither can reliably do the highest resolution. For that you'd need something with a 100 MHz or higher bandwidth."

Thank you for this valuable explanation. Your post has made it very clear to me.
