+1. Absolutely correct, and unavoidable. That's the HDMI handshake triggered when resolution changes.
Remember: (a) 720p - all ABC networks including ESPN, all FOX networks including sports channels and FX, National Geographic; (b) 1080i - pretty much everything else, with rare isolated exceptions such as occasional local networks.
Best workaround (if waiting 1-2 seconds for the HDMI handshake, if any, to complete is simply too annyoying)... try and keep the resolution changes to a minimum through some common sense techniques do deal with the underlying cause:
(1) Don't just always "browse" through channels sequentially from where you are, to "see/sample what's playing", as there's an obvious increased chance that you will be moving through channels where the resolutions are different. Instead use the GUIDE to see what's on, and when you find something you want to watch push OK on the cell. It's much more efficient anyway, to use the GUIDE for what it was intended... i.e. "to see what's playing on all channels" using an easy-to-read matrix/spreadsheet presentation.
(2) Minimize GUIDE pages to scan through by constructing "FAVORITES" channel lists of just those channels you actually might seriously ever watch.
(3) Don't watch anything "live", which increases the probability of encountering a resolution change as you change channels on the hour/half-hour. Instead, record everything you want to watch with one-off/series recordings, and then watch them when you're ready. And if the 1-2 second HDMI handshake is so annoying, just watch "a whole batch of 720p recordings, as a group", and then watch "a whole batch of 1080i recordings, as a group". As long as you remain on the same resolution value for any recorded program you play in the batch, there will be ZERO HDMI handshake needed.
To me this seems a bit over-the-top, just to avoid a 1-2 second black screen during the HDMI handshake. But if you have "native" consider yourself at least that much further ahead with your life that much more simplified, to at least get the optimal video processing/upconverting from the Oppo with minimal manual interaction. My own WMC Linksys DMA2100 media center extender doesn't have "native", but rather only puts out 720p or 1080i depending on setting. So I have to manually change the DMA2100 every time I watch/play a new program at a different resolution from the currently playing program.
But... the optimal video improvement from sending HDTV content to the Oppo at the "native" original untouched-by-DVR 720p or 1080i, well to me it's worth ANY amount of manual intervention I have to expend to see the terrific results on my 65VT50. If the DVR/STB is set to upconvert 720p to 1080i (so that everything output from it is 1080i and so that there now is ZERO HDMI handshaking from resolution changes, and thus you'll never be bothered by the 1-2 second black screen) to feed the Oppo which now has to convert faux-1080i to 1080p, well the results are NOTICEABLY INFERIOR and unsatisfactory.
