best dvd player under 50 image
Diver Dude
I have a basic home theatre setup with a low-end toshiba dvd player feeding into Onyko an receiver. From there the receive passes the video signal to my plama and sound to 5 speakers. For some reason as a dvd continues the audio gets out of sync (falls behind) the video. If I switch the chapters forward/back everything catches back up. The longer the movie, the more out of sync the two elements get. Cable signals do not have this issue.
What should I check?
Thanks for the great answer.
The setup in question is my secondary; a low end EDTV from Sylvania (6842PEM).
DVD player is a Toshiba SD-4000
My receiver is an Onkyo TX-SR504
Everything is connected using component cables (no HDMI on the tv or receiver). Sound from the dvd player goes to the receiver using a digital audio cable.
The receiver is fairly high end but the dvd player and plasma are not so I would imagine the issue lies with one or the other. I suppose the best thing to do at this point is just to swap in another dvd player and see if that fixes things.

Youâre experiencing what is commonly known as âLip Syncâ error most likely the result of an under-powered or poorly programmed image / video processor in your DVD player, AV receiver and/or display.
âVideo regularly undergoes digital signal processing over more than one frame of video causing the video signal to arrive later than the audio signal. Without the ability to digitally delay the audio signal to match the video signal in real-time consumers will continue to be exposed to the potentially annoying effects of lip-sync error, depending on equipment and source material. Lip-sync error becomes particularly irritating (depending on a personâs sensitivity) when the video is substantially delayed behind the audio by more than approximately 30 milliseconds.â
âVirtually all HDTVs now include some kind of video processing chip that performs complex tasks such as de-interlacing video signals, converting from the format/resolution of the source signal to the native resolution of the display, enhancing color appearance, removing noise, and so on. These video processing activities require that multiple frames of video be buffered and analyzed before each video frame is output and displayed. As a result, there exists a delay from the time the video is received into the TVâs input to the time the video is actually on the screen. Keep in mind that one frame of video at 60Hz refresh rate (common for todayâs HDTVs) corresponds to 16 msec. Since video processing typically requires anywhere from 2 to 5 frames of video to be buffered, this video processing results in 33 to 83 msec of latency. Humans are very sensitive to multimedia content where the audio is heard before the âlipsâ move (humans are less sensitive to perceiving audio that is slightly delayed behind the video). When the audio is more than 50 msec ahead of the video, the average viewer can detect this latency problem.â
âAlmost all HDTVs integrate audio delay electronics that automatically delay the audio signal going to the TVâs speakers to be in proper synchronization with the buffered video. However, when the audio is presented by a device other than the TV (such as by an A/V receiver), the TV no longer controls the audio signal and ensuing improper audio/video synchronization can be experienced.â
First things first check and see if any firmware updates have been released for your DVD player, AVR, and display. Next, check the ownerâs manuals for your display, DVD player and AVR to see if any of those components are equipped with some form of audio delay - either automatic or manual. If that fails to help you resolve your audio-video sync problem then your next step will be to track down the offending culprit(s). I suggest connecting your DVD player and AVR to a friends HDTV or ask a manager at one of your local A/V retailers if you can bring your DVD player and AVR to their showroom and try it with a couple of different displays, in each case always using the same connections that youâre at home.
If you provide the specific model numbers of your A/V equipment, a more detailed description of exactly how your equipment is connected, i.e., specifically which type of connections youâre using - HDMI, component, composite, S/PDIF, etc., and the specific type of source material, i.e., HD or SD video content, that is affected by the âLip Syncâ error, I or another Y!A contributor would (or should) be able to provide greater assistance.

Thanks for the additional information.
On page 58 of your Onkyo TX-SR504 Instruction Manual it states that the TX-SR504 receiver is equipped with an âA/V Syncâ setting. I would try adjusting the A/V Sync setting to see if it corrects the A/V sync error you're experiencing.
Quoted from page 58:
âWhen using progressive scanning on your DVD player, you may find that the picture and sound are out of sync. With this setting, you can correct this by delaying the audio signals. You can set it from 0 to 100 milliseconds (ms) in 20 millisecond steps.â
âNote: This setting is not available when the Pure Audio listening mode is used, or the Direct listening mode is used with an analog input signal.â

I'm wondering if a dvd that upconverts in HDMI will play movies in high definition?
pconn
Would I just be better off buying a hd dvd player? Want a surround sound system, but the only one I can afford ($350.00) says it upconverts in HDMI. Wondering what will the picture quality be like on my new Vizio 37" flat panel hd tv? Should I just go ahead and buy the hd dvd player and later buy an hd audio receiver with speakers?
Answer
in response to the last answer 720p and 1080i are considered true hd as well, infact in tvs under 50 inches you wont see a difference between 1080p and 720p unless youre within a few feet of the television. the blue ray is the only reason to go 1080p other then that most shows or sports broadcast via cable or satelite are filmed at 720p. but to answer your question the only way to get hd out of a dvd player is with and hd player or a blue ray
