krusty you might have missed an email from me because the problems i was having with channel 7 today turned out to be an embarassing case of poor reception due to rain! XBMC and the ServerWMC plugin was just erroring out with the stream ending prematurely so I thought it was this problem, but finally I tried things natively in WMC and was greeted with a "low signal" warning.
Once I fixed up my aerial connection everything was fine. I havent had any issues playing anything on channel 7 on all the occasions Ive tried.
Given what I just experienced today (low signal warning in WMC but XBMC and plugin just erroring/crashing) I wouldnt be surprised if what ferretlegs said about 1 tuner being dodgy could have some merit. Can you disable that tuner ferret, or try a different one etc? Although there does seem to be those DVBScramble headers in the WTV files I dont think its actually scrambled or encrypted. If they were actually encrypting some content but not others I highly doubt they would encrypt Dr Oz!!! More so a prime time premiere movie or something like that
In WMC setup I believe you can pick which tuners you want WMC to use. I wonder if you disabled the suspect tuner in WMC that this would flow through to ServerWMC addon as well, I think probably it would. So ferret perhaps disabling 1 at a time and seeing if you get a better result on channel 7
In better news, some changes krusty has been working on have now given me a very CONSISTENT channel change time! Evenwith the latest released changes I would still get variation of as good as 1 second backend timing but as bad as 8 seconds or more and sometimes even timeouts. The log file would show wanrings of more than 10,000 headers inspected in the WTV file etc.
Anyway, the latest changes ive been testing (will be in the next build) i am now seeing under 2 seconds consistenty whereas without these changes things were a bit more "all over the shop"
here are results of a number of channel changes under the current release version, and the upcoming build. Something to look forward to folks
