    I hope this is the right area.

    Anybody familiar with this ADS Scaler? It's really cheap but spec-wise it sounds good.

    It has been posted before. I wish I was brave enough to try it.

    Let us know if you plan to proceed with aquiring one.

    PS: The reviews seem mixed....

    I want some kind of doohickey with analog video inputs and a VGA output, which most scalers seem to have, but I want it to support Closed Captions, which I have rarely or never seen mentioned. Does anybody know of one? the product referenced does not seem to.

    There is no way CC can be passed through a scaler. The information is located on the vertical blank of an interlaced frame. Once a device changed it to progressive (or scaled to another resolution) the data will be corrupt and the only way to not show the corrupt data is by bypassing the data (in this case, CC) altogether.

    Of course you can't pass CC through a scaler, and computer monitors &c. couldn't decode it if it were passed through! What I am talking about is a Closed Caption Decoder, which would generate the appropriate text and superimpose it on the video at an appropriate resolution, just the way that the text is generated and superimposed inside the TV. External caption decoders exist, and perhaps could be inserted into a scaler feed line, but I would rather not impose too many processing steps in the video chain.

    I have yet to see a single CC decoder that has progressive out.

    Any more information on this box? I'm thinking of getting this for my projector and use it as a tv tuner. The PIP functions seem nice and it will make my projector work more like a tv set in away it seems.

    I checked the manual from http://www.adstech.com/products/HDUP...p?pid=HDUP1500

    It seems to do Close Captioning. Most tv tuners should have some sort of CC feature.
