Maybe this is just a "new not yet fully loaded" problem ... I hope so ... I just got a HR34 and a H25 installed today. While the tech was here we went thru the various functions and all seemed very good ... tonight .. when I press Guide ... I get the pop up window of the channel screen in the upper right and then a big light blue screen that EVENTUALLY fills with the guide info ... moving thru the guide (up/down) seems OK ... then I press EXIT to return to full screen view and it takes SEVERAL seconds before the guide is gone and the full channel view is returned ... this SIGNIFICANT delay did not occur while the tech was here AND it only seems to happen on the HR34 ... the H25 works as expected ... (and currently the H25 is set to 480i SD) so my real question is ... my area is "supposed" to get the new HDGUI tomorrow (1/11/2012) ... could I be seeing a compound symptom of new install guide download with new HDGUI happening at the same time and it is just coincidence that this started after the tech left?? I've seen a few comments that it takes a day or two for the HDGUI to settle to good response but so far I'm only seeing the "old" guide at this point.
