[QUOTE="ibanks, post: 91871, member: 26539"] Hi Phil-1, I would have replied sooner, but just returned from a week of vacation. To answer your question, no I haven't seen this same problem as you've described. I have another perhaps related problem in it's stead. Once I've completed a scan, and enter MP proper. I am able to recieve all analog channels, and changing between analog channels works. I am also able to recieve all digital channels, and changing between digitial channels works. Here's where I get into trouble. If I change channels from an analog one to a digital one, it works, once. The digital reciever side of the card will initialize (albiet a touch slow) and function as normal. If I change amongst digital channels it's okay, but when I go to change back to the analog tuner side all I get is a blue screen and audio static. The reason, I suspect, is that MP does not deinitialize\release the analog side of the ATI HDTV Wonder from the first time it uses it. Therefore the HAL and or MDM believe the analog card is still busy when it is again called later. I would think that this would be true of the digital side too, but suspect that the Microsoft BDA driver used on the digital side, may include some subawareness that handles init\denit logic automatically of it's own accord. Outside of MP's codebase. I haven't looked closer at my problem since before vacating. Maybe I'll learn more about it soon. As for your stuck channel thing... With the limited description of the symptoms, I'm not able to predicate a root cause. My first questions would be how are your channel listings and epg arranged? Are they in sync? In Media Portal Configuration, under 'project'-->'TV Channels'--><TAB>'TV Cards' make sure all of your analog channels are assigned to the analog side of your card and only to the analog side. Also all digital to the digital side and only the digital side. That may help. [/QUOTE]
