I'm new here. If I've got the wrong forum - I apologise.

I'm making MP3's from VOB files. My program gives me all sorts of options to set:

Bit Rate: 128 kBits to 320 kBits?
Sample rate: from Auto to 44100 or to 48000?
Channels: Auto to stereo
Stereo Mode: joint stereo or dual channel

and then even Use Variable Bit Rate!

Would someone please tell me their opinion as to what settings I should use?

Thanks in advance...

Bob

My opinion, but yours might differ.

Bit Rate: 128 kBits to 320 kBits?
128K is good enough for me. 320K makes the quality somehat better, but the files significatnly larger.

Sample rate: from Auto to 44100 or to 48000?
44100 is good enough for me. 48000 makes the files a bit larger.

Channels: Auto to stereo
Auto

Stereo Mode: joint stereo or dual channel
Dual Channel, it's more common.

VBR uses slightly less disk space, but I usually use FBR (Fixed Bit Rate), but that's just me. In fact all of the above is 'just me' :-)

FWIW to XP users: When you click on the 'Command Prompt' you are just causing the 'Command prompt' to be displayed. This prompt gives you access to NTVDM.EXE, the 'NT Virtual DOS Manager'.

Bitrate^
Even if you don't use high-quality speakers, imho, 128 kbps is not enough. I would go for 192 at least, or better 256.

Sample rate^
44100 and 48000 are no more than two different standarts, the 41000 is far more widespread. No difference in audio quality.

Channels^
Dual channel is encoding left and right independant, jointstereo is a kind encoding difference between channels, so the file would be smaller in most cases, though dualchannel seems more "secure" to me, regarding posiible quality loss
