For reviews I like to put the discs through Power DVD 4.0 and by checking the information it gives the kbps rate for Dolby and DTS. However my copy of Power DVD does not display dts, it says it is unavailable. I have downloaded a trial version of Power DVD 5 and this feature works on it, but my trial is over and I am back to version 4, and again it wont show it. Any ideas? Can't find version 5.0 in the shops. And the download is £40 which I don't want to do.
