[QUOTE="mm1352000, post: 788491, member: 82144"] Hi C.44 Still struggling with this problem? :( Let's start fresh, as my memory of this issue is not so good. Since I last spoke to you, I have learned two more things about FloppyDTVs: 1. Sometimes the driver takes a while to initialise after startup/resume. 2. FloppyDTVs *require* PID filtering on high bandwidth transponders because the firewire bus is not capable of handling the full transponder stream. I believe that last time we spoke we narrowed this issue down to something related to the TV card, but just to be sure... 1. Start TV Server. 2. Trash your channels. 3. Rescan. 4. Check HD channels work okay. 5. Make a short recording of an encrypted HD channel. 6. Reboot/power-off (do whatever you do to make the problem occur). 7. Start MP. 8. Play the recording. We expect the recording to play fine. If it doesn't then we prove that the problem is not related to the TV cards. If it does then we prove it is related to the TV cards. So please perform that test first, and just as importantly *provide me with the scan logs and a short list of examples of the channels that are problematic*. I will examine the tuning detail parameters for those channels in depth to check whether it might be caused by PID filtering not being applied. I note that the channels that you were testing in your older logs seem to be DVB-S2 non-backwards-compatible QPSK and that PID filtering was *not* used. NBC-QPSK may require PID filtering if the bit-rate is high enough. So far the PID filter is only enabled if the modulation scheme is 8 PSK or higher... Let's get this problem solved quickly! :) Best regards, mm [/QUOTE]
