I've used the DVR Studio pro evaluation version to try and burn .hav- files from a Handan receiver, using the DVD wizard. Everything else works fine, but the sound quality on the DVD is really bad - any views as to what might be the problem ?

The sound quality is identical to that what was recorded. DVR-Studio Pro does not re-encode anything, no video and no audio bit is changed. The whole process is just repacking from MPEG-Transport Stream to MPEG-Program Stream, but the content is the same.

In which way the sound quality is bad? Is it noisy or stuttering or playing too fast?

Hi - done some further testing and found that it seems to be the DVD player that does it - tried in an other player and the sound was OK. I still wonder why that is, since also the DVD player with the problem has a completely normal sound quality when playing store bought DVD's. The problem is not in the DVR Studio software, but was hoping you might be familiar with it and know the solution.

The sound problem is just disturbance - like a bad phone line or slightly untuned radio; timing and everything else is OK.

I then would guess a connection problem. Bought DVD often have DD5.1 sound, recordings often only MPEG. So maybe it's just MPEG-Tracks that sound bad.
Have you connected the DVD player by optical cable or via analogue wires?

The speakers are connected by analog cable - do you think that might be the issue ?

analog wires

It might be... But I was asking for the DVD-player connection ...

OK - it is an integrated home theater system, though, so there is no connection to any external apparatus other than the speakers.

Ah ok... Do you have any recordings which contain AC3 audio? Then you could switch to AC3 while playing the DVD. AC3 should be of much better quality than MPEG.

Errr.. this where my technical depth comes to an abrupt end ... wouldn't know AC3 audio if it came and bit me in the behind...

... Well DVR-Studio Pro lists all the audio tracks in the upper left corner. This could be an indications what the problem might be. If there only is MPEG listed, then this indicates that only the MPEG-tracks sound bad.

Only MPEG is listed... seems to imply that is what comes from the receiver. Not sure what that means for fixing the prolem.

Ok, maybe you find a TV-channel that sends in AC3 (Dolby Digital) and do a test recording. Then uncheck all MPEG-tracks on the 2nd page of the DVD-wizard and try that DVD. So we will know if AC3 sounds any different than MPEG.

Have you tried recordings from different channels until now?

Hello,

I encounter the same problem when making a DVD from .ts files.
I tried to burn recordings from different TV channels, with the same result (but found no channel with AC3 soundtrack).
My DVD player is a Sigmatek XM 380 pro, which plays almost all video formats (tried the DVD on a Peekton player as well, using the seperate analog sound output, but same result).
Only my PC computer can play back the DVD without any sound distorsion.

Thanks.
