I have to start from the beginning, i try to make this short

I used to watch DVDrip AC3 movies with "BSplayer 0.86 Build 493" - it very old version. I LOVE this player because of the sound - it has incredible/unexplainable low bass with DVDrip AC3 movies. (especialy with headphones, the sound volume is lower but bass is so good!) Lets call it "Superbass". Allso this player has this superbass ONLY then when i have installed TWO codecs from Nemo Codec pack - AC3 audio decoder and Claud/Dumb/Wavdest filters. Rest of the video codecs may be installed from various codec packs but the moust important is the presents of AC3 decoder and Claud/Dumb/Wavdest filters from Nimo Codec Pack. Many years i watched movies with this player...

...then i moved on to DVD-R 4.7GB movies because of better picture quality DVD-R movies have allso AC3 sound I downloaded DVD-R, Merged all VOB files together into one big VOB (i just liked that way). So when i open the big VOB with "BSplayer 0.86 Build 493", i did not had the superbass anymore. I solved the problem by opening a little DVDrip AC3 clip first and then opend the big VOB - then the superbass was there But...

...movie fans have never enugh. Now came along HD DVDrips (ofcorse i fell in love with the better picture quality). Some HD DVDrips have DTS sound some have AC3. Now, nomatter what i do, i dont have the superbass sound with that player anymore. Its with allmoust every HD DVDrip AC3 movies. Alltough they are with AC3 sound and player should use the same codecs i think (when i open media and see properties) I tried to open DVDrip AC3 first then big VOB and then HD DVDrip (all combinations) - no superbass

I have tried about 2 weeks now how to convert HD DVDrip AC3 sound into AC3 sound that regular DVD-R has - no success, no superbass. Seconday, i have tried to convert HD DVDrips with DTS sound to AC3 sound - no success, no superbass

I have tryed Besweet, Megui (converted about 12 days!!! and then crached), Fobar2000, BeLight and many more - no success.

So bottomline: Can someone please help me to convert HD DVDrip movies with AC3 (or DTS) sound so that they have regular AC3 5.1 sound like all DVDrp, DVD-s have. Please!
