I have a Samsung 52 inch 65f series which also has auto volume leveling. Its ads and specs spell out that this function will level out volume between stations and advertisement increases and the menu has an on and off for this function. However, I have found little to no leveling for either annoyances. I asked Samsung tech support about this feature and was told that the problem was signal strength coming from the supplier and their tv's are not capable of changing the signal strength coming from the station whether that be cable or over the air (I'm on cable). I again asked what this feature does and was given the same response. I was left with mis advertisement and selling features that do little or nothing for the product yet one pays extra money for. I also have found there are many functions that are available for the analogue tuner but are not available for the digital tuner. I know I haven't answered your question and hoping a technical person will come along and provide a more feasible response to both our inquiries.
i have a 47" philips lcd tv(47pfl7432d). one of the features is the 'auto volume leveling' option which is supposed to even out the difference in volume between the commercials and program you're watching. it's a useful feature because there's a usually a noticeable difference in sound volume between the show i'm watching and when the commercials come on. for my set-up, i'm only running regular tv stations via roof-mounted antenna(don't have cable tv or satellite yet). i receive about 15 stations, most of which have the analog and digital/hd equivalent(ex, cbs analog is 5.0 and cbs hd is 5.1. my question is that the 'auto volume leveling' feature only works for the analog stations. when i switch to the digital/hd stations, the feature will not let me select it. this is a little annoying since obviously if you have an hd tv, you're going to watch the hd channels. i've called philips support, they sent out a tech who couldn't answer the problem either. he's supposed to get back to me. the tv is only 4 months old and otherwise works perfectly. any thoughts???
