    A minor point is that I said that a tv signal capture wouldn't be better than a VHS output, not a VHS capture. Capturing video from a VHS source would add another level of compromise to the results.

    I figured a compressed mpeg played back on a tv would not be better than a tape being played on a tv.

    My experiences support this particular conclusion. Not scientific. Just subjective opinion.
    Not that I watch either on tv anymore.

    For the record I put Directv in a diferent category than tv in general. There is quite a difference even without HD.

    I typically capture broadcast TV using the tuner of a VCR and A to D conversion by using my Sony DV camera and Firewire into the computer. The connections are exactly the same as if I play back a VHS tape and capture in the same manner. I can tell you that in my experience the difference in quality between the off-the-air signal and a VHS tape is intuitively obvious to the casual observer.

    You're are truly a special person, your curiousity is to be admired, and I always have.

    Hmm! In your "doggedness" to put me in check you've ignored some of the simple principles of video transmission, everything is sublimated to its limits. I don't feel that you're "hounding" me but you may have out "foxed" yourself. I'm not against your conclusions, they're valid, I'm only stating that as much as you put into something, no more shall you receive.

    You know you can't make more with less but I'm looking to buy a Digital video camera, any suggestions?

    But I'm a non intuitive serious observer.
    Other than boredom I'm not sure why we're aguing about VHS.
    But I must assume you have better video capture ability than me. I don't believe either of us are going to be recording a lot on VHS in the future so I will leave the dead horse alone.

    My TV shows are on Tivo and movies are on dvd.
    I just use the VCR for the ocassional transfer to DVD from family videos.

    The point of this thread is to let loose and yea I think this debate about VHS comparative quality thing has no wings. I know that we'll find another reason to come here in time.:) LOL

    I do like the resolution used in cave drawings.
    But the conversion process looses some chroma thingies when putting them on DVD.

    I suppose we could talk automotive repair.
    That may be a little too far off topic.
    At least I know more about it. Then I could post a long one.

    Never under estimate cave paintings, at the time it was "state of the art."

    I got your point and I hate even the thought of discussing auto mechanics.

    It still seems you have quite a storm hanging over Florida. Is it still blowing hard near you.

    Yes it's blowing near me but not as bad and I get tomorrow off. I'm lucky, I'm not in a flood zone, when almost a quarter of a million people are without power and I'm online, it's mostly alright.

    I have cars in on the brain all week so this little world is my escape.
    One persons brain racking computer problem is my relaxation. No wheels, no grease, no fuel injection.

    I like it as an escape too. I used to think that a lucky evening was a corrupted operating system and a hard disk reformat.

    I'm glad you made it through with power.
    When the big ice storm knocked our power out for 10 days I found out how ill equipped I am to handle life without the comforts.

    For people like us it's not the comforts we'll miss, it's the not being online.

    When the power went out the notebook and dialup was my survival tool.

    Is the tree near the powerline behaving better I hope?

    I'm figuring you haven't backed up any movies during the storm. You'll have some catching up to do.
    I just read in another thread someone retracting their audio dropout accusation against RB.

    I think most of the audio dropout problems are from impatient people who don't wish to redo a movie from scratch when there is a problem.

    Every once in a while I'll have a glitch that doesn't have an apparent cause. I start from scratch and everything's fine. My only dropouts are when I goof and the Chinese film with subtitles has no sound. Whoops.

    I did a Bogart movie this morning, mainly because the weather failed to cooperate on Friday and Saturday. I have a camp thing going with the old classics.

    I like old classics but I have to watch them alone.
    My wife isn't into black and white or Jim Carey.

    I just watched Failsafe with Henry Fonda. I'm surprised I hadn't seen it before. Good movie.

    Yes, failsafe is a wonderful satire. I like the old black and whites because it was more theatre than todays movies are. Stages and scripts and acting, those were movies.

    I also like James Stewart movies, "It's a Wonderful Live." Basil Rathbone in Sherlock Holmes. All good stuff and black and white.
