[QUOTE="mm1352000, post: 1130670, member: 82144"] Hello First, I'd like to compliment you on your analysis. Great job! You looked in the right places and tried the things I would have tried. (y) This is rather odd. It's the first time I've ever encountered a tuner that exposed different interfaces for DVB-T and DVB-T2. Perhaps TerraTec were thinking that this would enable improved tuning speed. You're exactly right! :) TV Server is not able to determine the type of second "interface" (which is meant to be DVB-T). Both our ways of detecting the interface type - with the generic network provider supported network types, and with specific network provider connections - fail. As a result, we discard the interface. Attempting to add the card definition in the database is a clever trick... but I'm sorry to say it won't work, as you already have seen. TV Server doesn't store the tuner type. It always detects it when the tuner is detected. If the tuner type can't be detected then TV Server won't use the tuner, regardless of whether it is listed in the database or not. Yep, 100% correct. When you see the rapid skimming in TV Server it means that TV Server is failing to tune. Yep, trying different drivers was a good idea. So was trying the different network providers. I see you also increased the tune timeout - another good idea. ...and you even tried my patch for eMPIA tuners from -->[URL='https://forum.team-mediaportal.com/threads/pctv-292e-dvb-c-problem.128117']this[/URL]<-- thread. Really, you've tried and checked everything I would have tried and checked. (y) The only way this problem is going to be solved is by detecting the type of the second [DVB-T] interface correctly. I can only think of 2 ways to do that: [LIST=1] [*]TerraTec/Ultron fix their driver to make it compatible with TV Server's tuner type detection. [*]We [TV Server] find a new way to detect tuner types which can successfully handle your tuner. [/LIST] On the first point: you could try to contact TerraTec and tell them about the problem. Honestly, my experience with TerraTec/Ultron in the past is that they have been quite unhelpful. In fact I don't think I've ever received a response to any email that I've sent them. So, my guess is that they probably won't change their driver for us. But it doesn't take long to send an email, so... On the second point: TVE 3.5 already has a new tuner type detection method, which I think is probably similar to what DVBViewer are using. I can try to back-port a small part of that code into TVE 3 later today (or sometime this week) and see if it will work. Aside from that I think you've tried everything and there's nothing further you could do. Best regards, mm [/QUOTE]
