Hi there,

I am pretty new to this whole area.

I am planning on setting up a media server with all of my movies stored so they can be watched over network via a HTPC.

I have settled on video encoding with x264. However I can't make up my mind about whether I should leave the audio AC3 stream as is or rencode to AAC 5.1.

I can see advantages to both. Leave as AC3 there is no loss of quality and also will be very close to Bluray and HD-dvd spec. However AAC 5.1 should save space and is the mp4 standard and can be muxed into mp4 container.

I am leaning towards aac 5.1 encoding with the winamp encoder (CT based) but am not sure what bitrate to aim for. (As an idea for all my CD's I am happy with LAME at -preset standard which gives VBR about 192 kpbs).

What do people think I should do?
