Helpful Hints for MPEG & TV Video Adapter

Date Originated:

October 1996

Product(s) Affected:

LTE 5000

Symptom(s):

MPEG uses single, error-level checking technology. This technology makes the playback process for MPEG CD-ROMs much more sensitive to damage than audio CD-ROMs. Using caution when handling MPEG CD-ROMs will reduce annoyances common to CD-ROMs. The following table outlines some common symptoms of issues that occur when using a Compaq LTE 5000 Computer with MPEG and a TV Video Adapter. The table provides a solution if one applies or an understanding of the functionality of MPEG.

Suggestion(s):

Symptom	Comments
Playing back a captured image on a VCR causes the image to be of lesser quality than the original picture.	MPEG hardware limitations do not allow for like quality image translations. This does not, however, compromise the quality of the original picture.
Repeatedly clicking fast forward and rewind while playing a worn CD causes the MPEG video to slow, then the system to lock up.	Adjust the MPEG Playback sensitivity settings.
Temporary image discoloration, jerky movements, periodic pauses, video skipping, loud chirps or high-pitched squeals (For high-pitched squeals, refer also to the next symptom.)	Caused by dust, scratches, or fingerprints on the MPEG CD-ROM, or vibrations to the unit during playback Handle CD-ROMs with care, only touching the edges. Keep the CD-ROMs clean, and free from dust

Symptom Comments

While performing full-motion video capture in Video Work 1.5e, a high-pitched squeal may emanate from the speakers; and when a CAPTURE.AVI file is played back, no sound is heard. Use Solution A first. If the problem persists, proceed to Solution B.
Solution A
After each step, see if the the problem is corrected before proceeding to the next step.

Verify that all audio, TV, and VCR cables are properly connected.
If you have Microsoft Windows 95, click the Volume Control icon on the display; or select Programs, Accessories, Multimedia, then Volume Control. Adjust the various volumes found in Volume Control.

If you have Microsoft Windows 3.1, adjust the Wav and Line volumes and any other volume settings within the Compaq Sound System.
Remove any external microphone.

Solution B
If you have Windows 95, configure the audio to use Line-In (not microphone). To program RCA audio input into an AVI:

Open Volume Control, then Options.
Select Properties, enable Recording, click OK, select Options, Advanced Controls, and select the Advanced button. Then enable the Recording Input Monitor and Close.
Go into Options, then Properties and ensure that Line-In is selected.

If you have Windows 3.1, add sound using the following steps:

Open the Compaq Sound System
Select Rec (the highlight turns red).
Select Wav and Line (the highlight turns green).Sound coming through Line-In will be added to the AVI.
