So if I understand your setup correctly you have:
3-way splitter at POE: -5.5db
2-way splitter to Ceton/ATIs: -3.5db
4-way splitter in Ceton: -7db
Not exactly but accurate enough... the 3 way heads to the ATI's 2 (so, they are in that 'series' if you will and therefore a very strong signal) and I believe to a two way (my brother in law, a commercial electrician wired that piece) one to the Ceton and the other to the modem. On the line to the Ceton there is a splice with 10 ft. of 59 wire just before the Ceton, that splice was replaced by cable, as was the connector in the wall socket. At that splice (RG60-59) the signal S/N was fine. However, I may replace the entire run (30ft or so) with 60 and remove the splice (amp might just be easier/cheaper/more effective).
He also did check the line outside and the POE there was not a higher level of loss than expected... he gave me all the numbers and I recall thinking, normal for that length run (had the wikopedia page with loss/ft chart open). I don't see myself replacing just that 10'... the whole run or nothing, would kill the splice if I take the time (the RG60 is behind drywall)... I don't think the 10' run of 59 is hurting me that badly relative to the splice.
Today when I 'spot' checked the four tuners my lowest S/N ratio was 34, and my weakest tuner signal was -10.8, strongest was -5.8, although I was in the 'popular' range, 4 channels (didn't record the f's yet) were CBS HD, CNN HD, CNBC HD and Nick HD. In a quick test (watched about 40 minutes of the CBS HD) no problems found were seen. So, I have some logical testing ahead (or, put the damn amp on and cross my fingers that obviates testing).
On a completely different note (and, the note which originally caused me to research here). Occasionally (twice in the last 48 hours) while watching recorded TV I've gotten 'Windows has found a cable card tuner, would you like to configure: now, later, cancel' (not exact error).
Windows event log shows a recording event error (I keep an almost constant recording/s going while testing) which simply states the recording was manually stopped by another process. I'm assuming this is the segmentation error (or, something similar) frequently referenced in this thread but I do not know. I have only executed the Ceton software diagnostics once, and, it caused problems as I hadn't realized that my wife was watching on an extender and a recording kicked off shortly afterwards. I've used the diag tool within Media Center, but, only kicked off the Ceton one that once. I could not find log files in the Ceton directory, so, I assume when people reference the log files they are referencing those which are created by the Ceton tool (.zip file whose default save location was C:\\downloads).
I'm graduating to Ceton log point now (just built the new machine 3 weeks ago and haven't spent that much time on it, basic 'Assassin' config with Media Browser and MC Master.
I'm just really getting this thing up and running to retire the Vista 32 box, I have a few little quirks here and there. No deal killers, but, I'm also not retiring the old one just yet.
Thanks for all the help. Hopefully once I get edjumakated I can pay it forward.
