I wonder how well can you record multichanel sound tracks on to the super 8 stripe and have them decode. I would guess that Dolby Pro Logic II would be the best that is possible, or is it better to stay sterio?

You'll get Dolby Stereo from the machine you make the recording on. Playing the re-recorded film on any other machine will give substantial leakage between the channels but still gives a wrap-around Dolby Stereo effect.

Just try a recording on a bit of leader and run it back. You'll get an immediate idea of what is possible. But beware, stripe varies and you should always check down the leader of each reel before committing.

Thanks John,
Been considering getting a surround sound amp especially as the quality of the new releases justify it, I can sync to DVD but I have been more than happy with the quality of the stereo re-recordings I have done. Seeing as my stereo amp has just packed I wasn't sure wether it was worth the extra to go for a 5.1 set up.

Mark,

Your stereo is pure Left and Right (L R). Dolby Pro-logic starts as four channels Left, Center, Right and Surround (mono) and is encoded thru a matrix to Lt Rt (that's left total and right total). When it's decoded, it returns to LCRS when the matrix sums and differences the Lt Rt signals.

5.1, 6.1, DTS are digital formats and not matrixed to fewer channels and have stereo surround and a sub base channel (5.1) and three surrounds (6.1).

You can record the Dolby Prologic is the film is already encoded into two channels (the output from a DVD player with a L and R will be a prologic source.

You might as well get a 5.1 amp since most today will decode the 5.1 froma digital coax stream from the dvd player as well as DTS and 6.1.

Mark, why not go for the full pulse sync job film and Dvd. Master and Commander sounds great that way [Smile]

Get yourself an amp capable of DTS ES and Dolby Digital EX. This has a matrixed rear channel giving a total of three channels at the back. Richer Sounds had a Marantz amp, a 4600 I believe, for £150 that decoded these sound systems. There are others but the Marantz sounds rather nice for the money. Originally I think it was £400.
