Hi, i'm trying vdr-2.0.2 with my SkystarHD (not HD2) and in certain channels i have a weak signal problem. I've tried with kernel driver (I'm using Mint 14-x64with kernel 3.5.0-17) and also with latest dvb driver but nothing is changed. With my old disk Ubuntu 10.04 and vdr 1.7.21 I have no problem, what can be the problem???
Bye!
P.s.: i've also 1 Tevii and Mystique pci card but if i try with HD channels i see on tv not the right image but a lot of green square . what can be?
I have same problem as you with Tevii card - USB Tevii S660 and Dual TeviiS480. This problem occures with kernel >= 2.6.38.
The problem with green pixellatoin occures in channels in transponders with higher symbolrate, typically higher >= 30000 , e.g. transponders 0.8°W Thor 5 12015.00 H C16 Europe DVB-S2 8PSK 30000 3/4 Telenor, 66.8 Mbps NID:70 TID:41 0.8°W Thor 6 12034.00 V 17 K2 Europe DVB-S2 8PSK 30000 3/4 UPCD_Thor, 66.8 Mbps NID:1536 TID:705
Transponders with this parameters are also in other satellites, e.g. for SkyItaly ( 13E), Skylink (23E)
Problem occures in kernel 2.6.39. In this kernel is one of most great changes for modules - method ALGO_SW / vs. ALGO_HW for demodulator ...I contacted authors without any success .. Ivo Novak
Are the Italian sky channels with symbol rate 29900? Hi Luca

Yes, there are SR29900 ... But look there : http://www.forum.free-x.de/wbb/index.php?page=Thread&postID=23880 ... As I remember up to kernel 3.2 was possible to copy module ( ds3000 ) for S660 or S480 from kernel <2.6.38 and compile own kernel module ds3000.ko with old method ALGO_SW . But in higher version I'm not able compile this module due to depemdencies to other modules .... I have SatixS2Mystique dual card, where DVB-S2 HD works perfectly . I'm from CZ and I'm receving transponders from 23.5E and 0.8W. I tested some transponders SkyItaly with SR 29900 with Satix S2 and TeviiS480 ONLY for "locking" signal on transponders/channels due to scrambled signal ... SatixS2 - works correctly, S480 with old drivers, kernel <2.6.38 works, with kernel 3.1.x and old ds3000 - works too . With kernel >=3.2 - It don't work ... High, Ivo
Solution for problem signal with module ds3000: git clone git://linuxtv.org/media_build.git cd media_build ./build Running build until it starts to compile cc, about 30 seconds, and stop with CRTL+C find $PWD -type f -name "ds3000.c" Open file ds3000.c with a editor Search line: if (c->symbol_rate >= 30000000) And replace with: if (c->symbol_rate >= 29900000) Save file. make clean make -j 4 make install reboot Hi Luca
Hi Luca, your solutions with replacing ( SR299000 -> SR300000 ) in ds3000.c not working with channels on 23.5E(Skylink) and 0.8W(UPC) ...This method I tried also...If it works with SkyItaly I'm not able to try without decoding channels .. Thanks , Ivo
I'm sorry, I've forgotten to write another differences between transponders/channels ... It is symbolrate. Does work your Tevii card in transponders with higher bitrate ( >60MBps) ? e.g. : 13.0°E Hot Bird 13B 11785.00 H 53 HB8 Europe DVB-S2 8PSK 29900 3/4 Sky, 65.1 Mbps
TP with similar parameter is : 0.8°W Thor 5 11785.00 H C4 Europe DVB-S2 8PSK 30000 3/4 Telenor, 66.8 Mbps It doesn't work
23.5°E Astra 3B 11797.50 H 69 Europe DVB-S2 8PSK 27500 3/4 Skylink, 59.9 Mbps It works ....
