So I have a few problems I need answers for. Hope someone can help. Here are my questions:

1) So I tried to watch Harry Potter #4 via Cablevision On Demand last night. It was the HD version. For some reason, it was only coming in as Dolby 2.0 according to my prepro. Is it really possible that cablevision would transmit this recent movie in only 2.0??? Or could it be something with the cable box? (I do get network Dolby 5.1 feeds from the same cable box, so I don't think it's the box).

2) I did try to set my prepro (Krell S-1200) to convert Dolby 2.0 signal to DPLIIX so I could at least get some kind of surround sound, but it wouldn't work. The prepro manual does say it can take 2.0 and convert to DPLiix). Any ideas why the prepro would not convert to DPLIIX?

3) on a related note, if I have the prepro set to convert all incoming signals (2.0, 5.1) from the cable box to DPLIIX, why do I still get different surround modes when I watch network TV (depending on different recorded content of show and commercials)?

Please help. Thanks very much for any and all assistance.

Yes, it's very possible that an On Demand movie would only have a stereo soundtrack.

I can't help with the inability of your Krell to apply PLIIx to a stereo source. Does it work with other stereo sources such as CDs? Your system is more than 5.1? PLII expands to 5.1. PLIIx is for 7.1.

Some broadcast sources will be DD 5.1 and others will be stereo. Your prepro is likely set to process those sources differently.

Thanks. That would really suck if cablevision does that, and doesn't at least tell you this. The key benefit of on demand is that you can get an HD picture and surround sound, eliminating the need to rent/buy a DVD or bluray. I can't tell you how much it sucked to watch HP in 2 ch, knowing that we were missing all the surround effects. Yes, I do have a 7.1 system, so that's why I have signals converted to DPLIIX. I have the prepro set to convert cable DD5.1 to DPLIIX, and paused the movie last night to set the prepro to also convert Dolby 2.0 to DPLIIX but it didn't work.

So, does your prepro expand CDs to 7.1 when you apply PLIIx?

I did finally figure out that my prepro can indeed convert Dolby 2.0 via a discrete DPLiix button on the front face. For some reason it would not respond via the menu settings. So I'm good nowregarding the prepro and DPLIIX.

However, I still can't believe Cablevision would broadcast such a recent movie in only 2.0. It's really disgraceful and a ripoff. While DPLIIX certainly improves the sound, it isn't nearly as good as a native 5.1 signal from the original soundtrack.

No, you misunderstood. I HAVE heard 5.1 on demand with other movies. My complaint is that a recent movie like HP4 should not have been transmitted in 2.0 when it was available in 5.1 in theaters or on DVD/bluray
