Up conversion on some SD-DVDs results in a small picture

    I first attempted to upconvert using component video connection since my reciever will accept and switch this but not HDMI. So I blew the dust off of my HDMI cable but even over HDMI the picture is very small but centered on the screen. The component cables are still connected since HD DVD video can be carried over these and it keep me from having to switch sources on the TV as well as the rec.

    This problem doesn't exist on all of my old DVDs. It is a similar effect to when I am watching an standard def program on an HD channel for DishNetwork(which creates side bars) and then sending that signal to an SD TV(which creates top/bottom bars). But the picture from the DVD player is much smaller on the HDTV than the Sat pic is on the SDTV.

    Pulp Fiction, Rounders and maybe others both display in a small window but Shrek, Bridge to Terabithia and most of the others are displayed full screen.

    Probably the difference between letterboxed DVDs and anamorphic DVDs. Your TV should have some kind of zoom mode to expand the image on those letterboxed DVDs.

    My TV does have a zoom function but it appears to be disabled on HDMI. All is can select is 16:9 and 4:3. 4:3 makes the picture even smaller.

    This is probably due to the upconversion to HD over HDMI. Your TV assumes HD content is all native 16:9, so it locks it in full mode. The only solution for these non-anamorphic DVD's is to switch to the component inputs (which will be 480p - no upconversion for regular DVD's over component) and then zoom the 480p.

    Thanks, both of you.

    It does seem to only happen on the DVDs that come in boxes with the big "wide-screen" banner at the top.

    I have both component and HDMI connected so switching between them is not a big deal.

    The Oppo 970 will allow you to zoom non-anamorphic content over 1080i. One of the main reasons I bought it is for this very reason.

    But the Oppo isn't an HD-DVD player.

    I am interested in getting the A2 and want to clarify something....

    The issue noted in this thread primarily involves non-anamorphic 16x9 titles, correct? Does the A2 upconvert 4x3 material while maintaining the correct aspect ratio? It seems to me I read that certain Blu-Ray machines stretch the material (big no no for me).

    With my large collection of classic films I want to ensure they'll play correctly.

    Thanks.

    on the a2 you will see black bars on the sides when watching a 4x3 movie or television series.

    I believe if the flags are not enabled on the standard disc(s) the A2 can upscale over component.

    Jeff hits the mark in his post #6, with the caveat that my experience with the HD-D1 and a Tosh 34HDX82 set is that the set locks into "Full" mode when watching any content at resolutions higher than 480p via component AND HDMI. In other words, in my experience, upconversion is not so much the issue as the resolution at which you're viewing any content.

    For reasons I've yet to read an explanation for, the HD-D1 does indeed apply a mild stretch to 4x3 material. It looks like 1.66 to me but it's important to state that I see no distortion in the image. It's just clearly not 1.33.
