Then<br>check each channel one at a time (channel up / down) and check that you can<br>see all these channels with LiveTV and your recording tuners (as opposed to<br>your LiveTV tuner which is the least likely to get used for recordings).<br><br>What region are you in? Have you gone to <a href="http://retune.digitalready.gov.au" target="_blank">http://retune.digitalready.gov.au</a><br>to check whether you are affected by the channel restack? I don't suppose<br>you are eastern South Australia or maybe Murrumbidgee / Upper Murray given<br>your channel numbering, there have been various changes scheduled around<br>June / July / August which might align with your problems? You might need to<br>rescan to pick up changes in frequencies.<br><br>I'm just guessing here.<br>____________________________<br><br>Mark,<br><br>Thanks for replying.<br><br>OK tried changing the channels as you suggested and I thought you had nailed<br>it. I was unable try to access the back-end setup and fix it right away as<br>some waf recordings are happening (that are working). They are not scheduled<br>to finish for an hour or two.<br><br>There is one recording that is currently showing as zero bytes (still<br>showing as recording though) using tuner number 1. I changed the current<br>input to that adapter and there was nothing visible, just a black screen. As<br>it was recording it would not allow me to change the channel. So I stopped<br>the recording (it wasn't working anyway). Then retuned to that tuner. It<br>started on abc and was displaying a picture correctly. Changed to all the<br>other channels also, i.e. Prime, Win and Southern Cross. All displayed<br>picture and audio fine, so now I am baffled. It appears that the tuner<br>sometimes does not tune correctly.<br><br>I think I need to read up on unloading the tuners before shutting down to<br>try and get away from the warm start issues.<br><span style="color:#888888"><br></span>I'm assuming your source is DVB-T?<u></u><u></u></p></div><div><p class="MsoNormal">There were some adjustable tuning delay parameters in the card setup section of mythtv-setup which I had to increase a while ago to get reliable recordings from one of my DVB cards, though I can't remember if the symptom was zero-byte recordings or just failed recordings.<u></u><u></u></p></div><div><p class="MsoNormal">It's possible that when your box is cooler the cards take longer to get a lock?
