Did you restart your computer or something? Whatever you did between your previous test and this one helped... for a while anyway.Your logs tell me that scanning started and you were able to tune and scan quite a few frequencies. Channels were found and added to the channel list, then all of a sudden this happened:[COLLAPSE]2011-05-03 22:31:31.186797 [ATSC scan thread(8)]: ATSC tune: QAM checkbox selected... using Modulation 256Qam2011-05-03 22:31:31.190797 [ATSC scan thread(8)]: ATSC tune: PhysicalChannel: 39 Frequency: 307250 Modulation: Mod256Qam2011-05-03 22:31:31.210799 [(7)]: atsc:Tune:ATSC:tv:  Freq:307250 ONID:-1 TSID:-1 SID:-1 PMT:0xFFFFFFFF FTA:False LCN:10000 phys:39 maj:-1 min:-1 mod:Mod256Qam 2011-05-03 22:31:31.213799 [(7)]: atsc:using new channel tuning settings2011-05-03 22:31:31.215799 [(7)]: Setting Generic ATSC modulation to Mod256Qam2011-05-03 22:31:31.219799 [(7)]: GenericATSC: Set ModulationType: Mod256Qam2011-05-03 22:31:31.221799 [(7)]: dvb<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />ubmiting tunerequest Channel: subChannel:0 2011-05-03 22:31:31.224799 [(7)]: dvb:using existing subchannel:02011-05-03 22:31:31.226799 [(7)]: dvb<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />ubmit tunerequest size:1 new:02011-05-03 22:31:31.229800 [(7)]: subch:0 OnBeforeTune2011-05-03 22:31:31.236800 [(7)]: dvb<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />ubmit tunerequest calling put_TuneRequest2011-05-03 22:31:34.554990 [(7)]: dvb<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />ubmit tunerequest done calling put_TuneRequest2011-05-03 22:31:34.729000 [(7)]: dvb<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite5" alt=":confused:" title="Confused    :confused:" loading="lazy" data-shortname=":confused:" />ubmitTuneRequest  returns:0x8000FFFF - E_UNEXPECTEDCatastrophic failure[/COLLAPSE]Catastrophic failure really doesn't sound good! The other frequencies after that all failed to be scanned with the same error. When you tried to watch the channels that were found, the same error also occurred there...Okay, so where do we go from here? I'm not 100% sure. First, I don't know how you temporarily got the tuner to work. Do you have any idea what you did? My guess is that some other software or background service was using the tuner in your previous tests. Since only one program can use the tuner at a time, that would have prevented TV Server from using the tuner. Is there ATI media center software of some kind that you've installed? If there is, I'd recommend that you uninstall it at this point...Anyhow, that issue isn't so much of a worry as the "catastrophic" error. I strongly suggest you turn off your PC, leave it off for a minute or so, and then start it back up again. After that, set up your codec preferences in MediaPortal configuration and see if you are able to view the channels that you found in MediaPortal (I'd recommend that you don't use preview in TV Server configuration at this stage). If that doesn't work then post logs again and I'll be able to tell if we're getting the tuner initialization error, the catastrophic error, or something else is wrong. How does that sound?mmPS: Do you know if you are running the latest driver for your tuner?</blockquote>
