    Hi,

    Here are some quick numbers to start with:

    17:42 - 8 sec / SWR RP HD (Startup, first channel after switching on)
    17:44 - 6 sec / VOX
    17:45 - 3 sec / Kabel
    17:46 - 6 sec / SyFy HD (encrypted Sky channel)
    17:48 - 7 sec / RTL Crime HD (encrypted Sky channel)
    17:49 - 8 sec / Sky Krimi (encrypted Sky channel)
    17:50 - 4 sec / RTL Television
    17:51 - 4 sec / Das Erste HD
    17:52 - 5 sec / ZDF HD

    While it is clear that encryped channels take more time to be tuned, SyFy HD is tuned comparably fast with 6 sec while others need 7-8 sec. The Standard time for non-encrypted channels seem to be between 3 and 4 sec. It would be great if this can further reduced. The DD Card is set to "Stop" rather than "Pause". I do remember that I had changed this in the past but did not experience any difference.

    What are the times when using UNC paths (approximately) ?

    Now I am confused. I've not been using UNC paths recently and thought that you were interested in the RTSP files. Would you like the same under UNC?

    Apologies, I misread your question. Please expect UNC results for the same test channels tomorrow.

    Earlier in the thread you said:

    ...so I was interested in how much slower RTSP (with my recent mods) is compared to UNC paths. I can then compare UNC paths versus RTSP and look at where the extra time is being spent. I only have free-to-air SD DVB-T to test with, which has fairly fast zapping times anyway.

    Basically I'm trying to speed up RTSP zapping - if possible - so that (ideally) it's almost as fast as when using UNC paths. I'm not trying to speed up zapping generally i.e. for single-seat and UNC paths - I've spent quite a lot of time on that in the past, and I don't think there is much scope for improving it.

    Hi,

    I switched the same client to UNC and repeated the small test from above. Numbers in parenthesis are from yesterday's RTSP test.

    5 sec (8) / SWR RP HD (Startup, first channel after switching on)
    3 sec (6) / VOX
    2 sec (3) / Kabel
    6 sec (6) / SyFy HD (encrypted Sky channel)
    6 sec (7) / RTL Crime HD (encrypted Sky channel)
    5 sec (8) / Sky Krimi (encrypted Sky channel)
    3 sec (4) / RTL Television
    4 sec (4) / Das Erste HD
    3 sec (5) / ZDF HD

    @HTPCSourcer
    Just as a matter of interest, how are you measuring the timing?
    (In other words, what are your start and stop flags?)

    I suppose client + server log files for the UNC case may also be useful for highlighting differences.
