Audio Playback Too Fast, High Pitched.

On Telstar 5 a lot of the audio, especially the radio stations, plays back at a high pitched rate that sounds like Alvin and the Chipmonks! Is there some way to slow it down so it sounds normal?
This program sure has a lot of odd problems! Besides the strange sound and crashing when I try to scan a second satellite the video freezes if I resize the window and it often won't remember changes in the settings.
Is there a more stable, debugged version that's due out soon?
DD seems to have a long way to go but even with all the bugs it still works better than the other programs I've tried such as MyTheatre, SesamTv and ProgDVB that wouldn't work at all.

Which audio codec is in use ? Some of them, such as nVidia audio decoder, are not able to play back some particular streams (mono stream - very low bandwidth / very high bandwith, ....)
and it often won't remember changes in the settings.
Settings are not saved if DD crash before normal exit, the settings.cfg file is updated at exit. This is a good thing regarding the fact that if a wrong setting makes DD crash, there's no need to save this bad setting... Saving this wrong setting would result in a crash of DD at start!

I've no idea what it is or how to change it but it works using DVBapps instead of DD.

Found it under Video, of all places! It said Elecard LII was in use and I changed it to Cyberlink and it works OK now.

It may not have been the codec's fault. As long as you've got it working don't worry about it.
There are some channels that use odd sample rates. If the codec doesn't tell the sound card what the rate is or the card doesn't change you'll get audio of the wrong pitch. Some codecs play along better with direct show than others, they actually resample the audio in real time, CPU intensive. Many channels on that bird are very highly compressed and they do things to save bandwidth. It would not surprise me at all to find several there that use lower sample rates than the rest.
There's a shopping channel in the US that uses 44.1 instead of 48khz. Silly fools.
