[QUOTE="Syrel, post: 1124788, member: 145506"] Hello, I'm struggling with a TBS6618 DVBC card w/ CAM+CI, and cannot fix it. The symptom is that the card works perfectly until the first Standby (S3) - Resume cycle. After resume, the card appears no longer accessible by TV Server. Initially I had issues with BSOD upon resume, using driver 1.0.0.4, but then contacted TBS support (Steven) and they were kind enough to fix the driver for me. Now I no longer have BSODs, and the card is still there in Device Manager after resume, but TV Server is not able to use it any more. Various messages like No signal, Channel not found, etc. are thrown. Since I've been trying to debug it for 3+ days, I've discovered the following: [LIST] [*]If I stop all users of the card before standby (TV Server service), and start them again manually after resume, there is no issue. (This needs to be further validated, since I've only tried this ~5 times.) [*]When the card is unresponsive after resume, and I stop the TV Server service, go to Device Mgr and disable/re-enable the TBS card, everything starts to work properly again. (This is consistent and verified.) [*]When the card gets 'locked' after resume (not working from TV Server's point of view), it still appears to partially work from TBS Viewer. This means that TBS Viewer does not complain about the card being unavailable or not responsive, and upon channel switch I see the progress bar gets updated, and keeps moving. It seems the card itself can tune, stream is there, and certain program info is indeed retrieved, but the filter graph cannot build properly and there is no audio/video. I'm definitely no expert on filter graphs, but it's like something in the graph does not provide video/audio. [*]There are no exceptions reported in the TV Server's log, but the log suggests that even if the graph builds properly, there is no signal coming. [/LIST] I have tried to change all settings, including delays, stopping card instead of pausing, changing the TV Server service startup to delayed, etc. As a result, now it seems that when MediaPortal is not running, just the TV Server and it's settings utility, sleep/resume works (I have yet to test this further, I did ~4 tests yesterday evening and got excited that it works). At least in the TV Server config utility I can tune in to any channel and I get video/audio after resume. But the same does not work from MediaPortal, and once I get the 'No signal' error, the card does not provide video/audio in the TBSViewer as well, and the only way to make it work properly again is to disable/reenable from Device Mgr. I'm on Win7 x64, and MP 1.10 with the latest patch from this thread of course. Can anyone suggest anything that I could try? [/QUOTE]
