How to do DVD settings?

· Quality Control
Select the video quality for the output here. In general, the higher the video quality, the higher the bit rate and the larger the file size, vice versa.

· Transport streams.

This option is available only when you choose MPEG-2 as the output option, and choose Format under Video Settings as Customize. It specifies the MPEG-2 TS format. This format is specially used in broadcast applications such as DVB and ATSC. For normal DVD players, this option is not recommended.

· Compatibility
Use progressive scan for MPEG-2/DVD
Both progressive scan and interlaced scan are employed by MPEG-2/DVD, but some old DVD players cannot play the videos encoded with progressive scan. The image quality (depends on your TV set) of progressive scan is more stable and sharper than that of interlaced scan. For most recent DVD players, progressive scan is perfectly supported.

· Use MP2 as the audio encoding format
The sound quality of MP2 and AC3 are almost the same, and they are both DVD audio encoding standards, but some European DVD players do not support AC3 audio. If you find the created DVD is not hearable, selecting this option should be a help.

· Use 44.1kHz sample rate
This option is provided to get a better audio quality for MPEG-2 video.
The default sample rate of MPEG-2 is 48kHz, while most audio files' sample rate is 44.1kHz. Unselecting this option will cause the loss in audio fidelity and increase in the file size when encoding MPEG-2 Video, as the sample rate of the audio is changed from 44.1kHZ to 48kHz.

· DVD Language
Select the appropriate audio language from the Code list for the created DVD. Please make sure that the language you choose here is accepted and selected as the preferred audio language by the DVD player.
