Here's the EXTREMELY UNSATISFACTORY answer, from an on-line chat I just had with Comcast customer service, transcript pasted below. If anybody from Comcast monitors this forum, I hope you realize why you are losing subscribers.
analyst Benjamin has entered room
Benjamin: Hello Gregory, Thank you for contacting Comcast Live Chat Support. My name is Benjamin. Please give me one moment to review your information.
Gregory: My Issue: In On Demand, if I start with "find by network" and go to NBC, episodes of Saturday Night Live in HD are free. But start with "find by TV show" and go to SNL, it won't let me watch those same episodes unless I sign up for Streampix at $4.99
Benjamin: Great to have you on chat, Gregory . I hope your day is doing just fine.
Benjamin: I understand you would like to watch Saturday Night Live in HD, is this correct?
Gregory: No. Read the question I asked carefully, please.
Benjamin: If I understood it correctly, you are trying to watch Saturday Night Live through find by TV show however it will require Streampix Subscirption. Is this correct?
Gregory: No! the same episode comes up as free if I find it by network, but if I find it by TV show, it says I have to sign up for Streampix. It should be the same no matter how I find it. If it is free, it is free.
Gregory: Or it should be free, that is.
Benjamin: Let me go ahead and check on your account further to verify if the program is part of your channel list.
Benjamin: Please give me a minute.
Benjamin: Gregory, I see here that the reason why it would require you Streampix Subscription is because if you find it by TV show, it will give your all the episodes of Saturday Night Live, that includes past episodes. This is not free unless you are subscribed to Streampix. If you try to wath it in NBC, it will only give you the latest episode, you will not be able to view the previous episodes.
Benjamin: If you watch it the latest episode only through NBC, yes you can watch it free since it is part of your channel. However, if you watch all episodes inlcluding the previous ones, this is no longer free. Subscirption to Streampix is required.
Gregory: I understand your answer. But please be advised that this is terrible customer service -- not you, the On Demand guide. When I was trying to watch SNL the other night, if I had known I could get it for free simply by looking for it a different way, I would have been able to watch the episode I wanted. There is no explanation of this. Terrible. We can end this chat now. Good-bye.
