Hi all,

Having problems with playing back of recorded TV that has been transmitted in the "Dolby Prologic" format.

Current sound setup uses only a SPDIF Optical connection from PC to AV Receiver.

When watching live TV, Audio is fine for both "Dolby Digital" and "Dolby Prologic" sound formats. If I record then playback "Dolby Digital" TV it is also fine.

When I record TV transmitted in the "Dolby Prologic" format and then play it back the AV Receiver is detecting the sound output as "Dolby Digital", thus I am not getting audio.

I have updated to the latest nforce drivers, also tried the AC3filter 1.11 with no luck. I have also played the recordings with WMP9 but same result.

Any ideas?

Not sure why, but I changed the recording format from mpeg to ts and this seems to have fixed the problem. I guess that the mpeg compression could not handle the "Dolby Prologic" data format.
