0x5cd, received 5/22.
My main TV is an old Toshiba "HD-ready" CRT capable of displaying only 540p or 1080i. It scales everything else to one or the other of these. Consequently I just have 1080i enabled in my HR-20/700 setup, with native off. I feed the signal via component through an Onkyo receiver which is old enough to have component but not HDMI connections. As there is no HDMI involved there at all, I have no handshaking issues.
But I do have a simultaneous HDMI run into the guest bedroom on the other side of the wall, feeding a Sanyo 720p set, which takes the 1080i output from the HR-20 and converts it to 720p. This is seldom used, but as a result of this thread I went in and played around with it today. I did not find any evident handshaking problems.
I have an HR21-100 that has developed an HDMI handshake issue with my Toshiba 65H84 RPTV since receiving the 0x5cd firmware. The HR21 connects to my Toshiba via a 4x2 HDMI switch > HDMI splitter as follows:
One output from the 4x2 switch (which also carries feeds from an HR24-500 that hasn't received the update yet and a Roku box) feeds an HDMI splitter whose outputs feed the Toshiba RPTV and an Insignia LCD. There are no issues with the other sources and the Toshiba RPTV and the issue with the HR21 and the Toshiba is not an issue with the Insignia LCD.
The other output from the switch feeds an Actiontec wireless HDMI transmitter whose signal is sent to the wireless HDMI receiver one floor above to a Samsung LCD...all 3 sources are received and displayed without issue.
Now, the issue I keep referring to is very similar to what others are seeing but specifically what's happening is that everytime I change channels on the HR21 my Toshiba RPTV's picture turns green. I then need to cycle the switch's inputs to correct it which actually results in the HDMI input flickering the first time I cycle back to the HR21 and only after a 2nd cycle does the picture return to normal...changing the channel gets me right back to a green screen. Keep in mind that the other sources display without issue during this cycling process. My work around (as others are also using) is to use the component output from the HR21 to the Toshiba RPTV! What's ironic about this is that I recently stopped using component and composite outputs from the HR21 due to the annoying HDCP message that was popping up with the last firmware version. Isn't this fun?!
For the record, my two HR22-100s have also received the firmware update, one is connected to another Samsung LCD, the other is connected to another Insignia LCD, no issues with either one.
Anyway, trying to remain optimistic here, I've been looking for an excuse to upgrade the old Toshiba RPTV and this may be it...thanks DirecTV!
