Thanks for your reply. Here's what I know so far:

1) The reason it is only the last two disc, is because they are the first two disc I have purchsed and imported since I upgraded. All the files imported prior to that time play fine.

2) I tried using a different external plextor 48-24a drive and produced the same negative results.

3) Microstudio still works fine with both drives that I have tried. So I know it's not an issue of the plextor drive going bad.

4) I tired re-installing/updating the firmware for the drives from Plextors, no change.

5) When I re-import a previously imported disc, it looses it's audio as well.

6) Occaisionally at the very beginning of an imported track a loud pop will come through the speakers for a split secound, and then nothing but the graphics with no sound, and on some tracks the graphics will show just for a second and then everything stops and the track deletes itself from the play list.

7) Like you, I am certain this is not a Hoster problem, but I don't know where to check next.

8) I know the new version of hoster I used to install with is fine, becase i saved the program to as removable USB drive ande used the same file for both my computers (I own two liscense), and it works fine in one and has this problem in the other.

9) Unfortunately, I tried to revert back to an older version of Hoster in the problem computer and I have the same problems.

10) Tracks played from the orginal disc have the same problem of no audio when played in Hoster.

These are all the things I've obseved and tried so far.

I'll send you the DXDIAG information tonight when I get home and maybe you can make some suggestions from there.
