analog sound works very well but ac3 or dts flickers and video playback starts fast than slows down and so on

Same playback issues here (I'm on XP SP3 using the 2_18_0008 creative driver (X-fi xtreme music). other info: Nvidia gpu with 178 whql driver, amd cpu.)
Found out that if i untick DTS and AC3, Digital can be set and it won't compromise playback.
Is this same as having it set to Analog (Digital/no AC3/no DTS)?

You might check to see if "Adjust Refresh Rate" has been selected under video player settings. If it is selected, try unselecting it. That's helped me in the past.

Pasqualz: Thank you for a very well-written description. This level of detail is what really helps nail things down and makes it much more likely that someone will work to resolve your problem.
I have discovered the source of this problem, however, I have not identified what I think is the best fix. This issue is related to the way the soundcard (SB X-Fi in this case) driver handles its mix-ahead buffer. The driver requires a minimum amount of valid data between the play cursor (current 'read' location) and the write cursor (next safe 'write' position). This amount is fixed (as far as I have been able to tell) for each output data type, but varies by soundcard and output configuration, making it difficult to use a constant value. It appears that the hard-coded chunk length (minimum buffer write size) is enough to satisfy most existing hardware, however, the X-Fi series uses a much (5x) larger window (write - read) for encoded AC3 and DTS streams. There is no way to query the card for this window length prior to starting playback (that I have found), so it creates a bit of a mess. Hard coding a larger chunk length would increase latency unnecessarily for all other stream types/hardware.
I know this is a long answer, but I wanted to capture the information somewhere. I happen to have this soundcard and want to fix this issue, so you can expect that I will keep plugging away at it until I find an acceptable solution.

I will submit a debug log this evening when I get home. Any help is appreciated.
