    TV-Server: XP SP3 + MP 1.0.0.0

    Client: Vista64 SP1 + MP 1.0.0.0

    Playing a pre-recorded tv program (h264 .ts file) via My TV -> Recorded TV results in audio stutter/dropped audio/clicks

    If I browse to the Mediaportal recording folder in network share using My Video's and play the same .ts file there are no audio problems.

    Both Television & Video have same audio codec settings under MP Config on client

    I also experience audio stutter when watching Live TV on the client.

    It is very strange, originally i thought it must be either a network bandwidth problem or something to do with the audio codecs on my vista client. However why does the video play fine under My Videos but i get stuttering under My TV Recordings???

    The audio stutter can be described as suttering bits of silence inserted into the audio with occasional clicks.

    Graphedit reveals both MY TV -> Recorded TV and My Videos have the same rendering path

    Southpark.ts -> Audio -> AAC Monogram -> Default DirectSound Device
    Southpark.ts -> Video -> Cyberlink H264 codec -> EVR Input0

    The problem has something to do with RTSP i think, i managed to fix it using the following steps

    1. I updated to latest SVN 21813

    -> This didn't fix problem

    2. Then I edited mediaportal.xml on the client that stutters and added <entry name="usertsp">no</entry>

    -> This gave me unable to timeshift error so i undid this change

    3. Then I edited mediaportal.xml and added <entry name="recordingpath">Z:\Mediaportal Recording</entry> and <entry name="timeshiftingpath">Z:\TIMESHIFT</entry>; Z:\ is a mapped network drive to the TV server computer, i guess this fools MP into thinking the tvserver is local therefore bypassing RTSP?

    -> This fixed the problem, however i now occasionally get a patch of video corruption in the Live TV, for a secound or less affecting a small area of the video. Not sure what is causing this problem, but it is not very bad, and much better than before where i had problems with the audio.
