[QUOTE="xurr, post: 499512, member: 20299"] I kept experimenting, trying to find a solution or at least the answer to "is this a MediaPortal TV Server issue or a driver issue" but I still got no clear idea about what's going on here... What I discovered is that basically only one of the two cards can be tuned at the same time: I changed TV Server code so that the card priority is ignored (overwritten with random values), this way I can see that by starting/stopping timeshifting (either from a client or from SetupTV) both cards do work, but only one at a time. This means that graphs are built correctly, there is no apparent difference between which card is started first, still the tuning fails if I try to start a second timeshifting from another client when one card is already timeshifting. The only thing I see in the logs is the "Timed out waiting for PMT after 10 seconds" (usually PMT is found in less that 1 second). I cannot understand how the whole PMT stuff is handled in TV Server code, so I stopped my investigation here. Meanwhile, I posted also on the Hauppauge UK forum... [/QUOTE]
