I'm using diseqc.conf and the gotoxx patch, it works very well! I mgot gotoxx working too. For some reason my motor doesn't work with 18V so needed to change it to use 13V. However I'm adding fourth tuner soon. It will be connected to the motor dish too. I have been examining vdr's Device Bonding feature. If two devices are bonded and Diseqc is enabled, vdr will compare the diseqc strings of the already tuned master, with the diseqc string of the new channel on the other device. If they match, channel change is accepted. So basically it should work if you simply have same diseqc config for both bonded devices. However, there is a problem that also the polarisation and low/high frequency range is compared. This means that the bonded device is restricted to same polarisation and frequency range. This would need some patching in dvbdevice.c.. And what exacly would you want to patch there? Bonded devices are connected to the same antenna cable, and on one cable you can only convey one polarization (H or V) and one frequency band (high or low) at the same time. So the restriction to same polarisation and frequency range is necessary for device bonding, and I don't see how using a motor dish would make any difference there. To connect 2 tuners to one motor, need to do a little patch to restrict both tuners to same source, instead of restricting high/low freqs and polarisation, as both tuners would have own cables. Oh, I see. I guess I misunderstood your posting and assumed there was only a single antenna cable. I have made ugly hack to dvbdevice.c to send diseqc positioning commands using only tuner which is connected to the motor. Basicly I just took fd_frontend of device connected to the motor and use it for diseqc commands ioctl(). If both tuners are used with my hack as is, motor is turning wildly between satellites on source change. Lets take an example: At begining both tuners are tuned to 1.0W and I change to channel which is on 13E. Tuner #1 stays tuned to 1.0W and wants motor to go there, and at the same time tuner #2 is trying to get motor to 13E. So some patching is needed to restrict selected tuners to same source with eachother. So what you're trying to do is to bond the two devices in a way that only takes into account the antenna position. Maybe you could achieve this by changing cDvbTuner::GetBondingParams() in a way that extracts the positioning part from the DiSEqC commands and returns just that. Then, with bonded devices, it should use only one of them for positioning, and both will only tune to transponders from that position.

I think it's enough to just return the position, like S1.0W.. With GotoXX patch, the positioning DiSEqC code is actually just G for each satellite, so there is no difference to be found there! Also the tone/range checks need to be removed from SetFrontend. This is easy to do as a hack but much more tricky to have some clean solution that would allow old behaviour as well.. The GotoXX patch itself is very clean and easily completely disabled with the setup switch. While Klaus is listening, perhaps you could consider including this? GotoXX essentially replaces all Rotor and RotorNG plugins, and is very easy to setup because it can automatically tune all satellites without any configuring.

Hi, your opinion is right for diseqc installations with only motor. But it could be also combined with commited and uncommited switches. I'm using 2 dish installation, one fixed multifeed with 5 LNB's and second dish on motor with one LNB. In my installation there are 3 switches in cascade - first switch is 2 input uncommited with 2 4-input commited switches connected to uncommited switch. The motor is between DVB card and uncommited switch to prevent high current flow through diseqc switches. For any of fixed LNB the diseqc.conf looks like (example for LNB on C input of commited switch connected to 1st input of uncommited switch) S23.5E 11700 V 9750 t v W15 [E0 10 39 F0] W15 [E0 10 38 F8] W15 t S23.5E 9 V 10600 t v W15 [E0 10 39 F0] W15 [E0 10 38 F9] W15 T S23.5E 11700 H 9750 t V W15 [E0 10 39 F0] W15 [E0 10 38 FA] W15 t S23.5E 9 H 10600 t V W15 [E0 10 39 F0] W15 [E0 10 38 FB] W15 T For LNB on motorized dish it could look like S7W 11700 V 9750 t v W15 [E0 10 39 F1] W15 [E0 10 38 FC] V G W15 v t S7W 9 V 10600 t v W15 [E0 10 39 F1] W15 [E0 10 38 FD] V G W15 v T S7W 11700 H 9750 t V W15 [E0 10 39 F1] W15 [E0 10 38 FE] V G W15 V t S7W 9 H 10600 t V W15 [E0 10 39 F1] W15 [E0 10 38 FF] V G W15 V T (remark that output of motorized LNB is connected to D input of commited switch connected to second input of uncommited switch). So practically every combination of switches and motor is possible to use. Best Regards, Ales ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
Re: [vdr] HD Test clip(s)
Hi! As an USB receiver I use the TeVii S660. Works fine. Regards, Stephan. Am 02/16/13 14:09, schrieb th_zieg...@gmx.de: Hi, Are there any VDR-compatible (I'm using e-tobi 1.7.29) HD test clips, available somewhere on the net or can s.o. provide one? For better comparisson with SD, the a clip from the German ARD- or ZDF-news would be nice. A few minutes is sufficient. Background for those who are interested: I'm using DVB-T based vdr since a couple of years now for in-house streaming to various devices. I plan to add a DVB-S card to support HD. I'd like to check if HD-streaming works with my current setup before doing the investment in a sattelite dish etc. Any other hints regarding what USB DVB-S receiver, sat-dish, etc. works well is also welcome.
