The latest changes you can see: http://jusst.de/hg/multiproto/log So many changes went in after 5822, head is 5917 though only till 5916 is applicable to you. Also it looks like the register initialization in the PCTV452e driver seems to be different from budget_av and budget_ci, i don't know the exact reason for those changes, maybe has to do with something with that hardware, but then i can't make out anything clearly from it.

By the way, is there any method for getting more error information from the device ? Do you know whether packets in error are discarded by the device without being passed to the device driver ? If so, is there a programmable option to pass error packets through to the device driver and application ? if you load the module with verbose=5, you get a load of information from the STB0899 driver. Please try applying the patches from the jusst.de tree on to your tree and see whether it helps in some way.

I tried the following 6 channels on Astra 19.2E: Das Erste:11837:h:0:27500:101:102:28106 ZDF:11954:h:0:27500:110:120:28006 3sat:11954:h:0:27500:210:220:28007 Rhein main TV:12633:h:0:22000:208:308:12614 DW-TV:11596:v:0:22000:1000:1001:10020 QVC Germany:12552:v:0:22000:165:166:12100 The first three channels have symbol rate 27500, the second three have symbol rate 22000. I captured one minute of data from each channel and then ran the files through TSReader to check for errors. The data from the channels with symbol rate 27500 is perfect. However, the data from all the channels with symbol rate 22000 show errors, typically in the range 300 to 500 continuity errors in a one minute period, which works out at around 1 in 300 packets lost on average. This seemed to indicate the problem is linked to symbol rate, as you suggested. However, I then repeated the test on Astra 28.2E, which has a stronger signal at my location. I tested a couple of channels which have a symbol rate of 27500, for example Sky News. Both of these showed continuity errors. Therefore the problem cannot just be linked to symbol rate. I then performed a full scan of Astra 19.2E and 28.2E using DVBViewer under Windows. This scan indicated that all the above channels on 19.2E which have symbol rate 27500 and show zero data loss have a FEC parameter value of 3/4, whereas the channels on 19.2E which have symbol rate 22000 and show data loss have FEC 5/6. On Astra 28.2E, the channels with symbol rate 27500 (e.g. Sky News), which show data loss have FEC 2/3. This leads me to wonder whether the dependency is in fact FEC related, as only FEC 3/4 gives an error free stream in the above tests. If I could find an error-free channel with symbol rate 22000 and FEC 3/4 this would eliminate symbol rate as an issue. However, there do not appear to be any channels on 19.2E or 28.2E configured in that way. Of course, there are other devices out there which also use the STB0899 module. Could anyone who is familiar with this module shed any light on the issue ? I should emphasise that all the above channels are error-free under Windows on the same hardware with the same feed, so the problem doesn't appear to be related to signal quality.

[linux-dvb] Pinnacle PCTV Sat HDTV Pro USB (452e) packet loss
Although this device is not yet officially supported, I've been trying to get it working following success reported by others in an earlier thread. I've followed the instructions in the DVB wiki entry for this device, and have succeeded in tuning the device using the patched version of szap, and recording a transport stream (using cat /dev/dvb/adapter0/dvr0 recording.ts). However, the transport stream shows up discontinuity errors which manifest as glitches in the playback. From the stats produced by TS Reader the rate of loss is typically around 1 packet in 700, though it varies from run to run. I realise the simplest explanation for this would be a poor quality signal. However, the device performs flawlessly under Windows XP in exactly the same hardware configuration (same computer, dish, and sat feed) when tuned to the same channels. This seems to rule out signal quality as a cause unless the linux driver does not configure the device's error correction properly. Is there any possibility this could be the case ? I've also tried running the linux configuration on two different computers - an AMD X2 4600 with Asus M2NPV-VM mobo, and a Via EPIA5000 system (with a PCI 5-port USB2.0 card). The same problem occurs on both systems. I'm using kernel version 2.6.18-2. I also have two DVB-T USB adapters which work with the same software configuration with no packet loss. The channels I've tried are BBC 1 London and BBC HD. Obviously, the data rate is much higher on the HD channel. I've cross-checked with the XP configuration to make sure that the frequencies, polarity, etc. are correct in the channels.conf file. Note that during the BBC HD trial from Crystal Palace I was able to record this channel from a DVB-T adapter without packet loss even on the EPIA5000 (533 MHz Via Eden processor). I'm unable to determine at what point in the processing chain the packets are being lost. I temporarily inserted some checks for continuity errors on a specific pid in the 'dvb_dmxdev_ts_callback' function in dmxdev.c. This showed packets had already gone missing at this point in the driver. I don't know my way around the code well enough to be able to pursue it further. In particular, I can't tell whether the packets are being discarded somewhere in the driver, or within the device itself. The only kind of errors which I detect are continuity errors. Does the device filter out all packets in error or does it pass them through to the driver with the appropriate error flags set in the packet header ? Has anybody succeeded in getting an error free transport stream from this device ? If not, are there any ideas about where the problem might be ?

I have no idea what that wonderfully vague description means. Is there already a driver for this device which I can test? I can support you on testing the driver, but where can I find this? I rather doubt that there is a driver(s) per se for the 452e. Manu has indeed produced some experimental drivers for some PCI cards that use the same frontend portion as the 452e, and while these same drivers have been, from my casual observations, extended for use with a few other similar PCI cards, I have not seen mention of their extension to USB. In order to do so, in the case of the 452, one will have to figure out how the FX2 is behaving, and then tie these two sets of elements together (i.e. glue code between the components, which offers device level support). I just found the device twice on http://www.linuxtv.org/wiki/index.php/DVB-S_USB_Devices . First in the unsupported DVB-S USB device ans second in supportet DVB-S2 devices. So I understand that there is DVB-S2 support for this device but no DVB-S support. Is that right? I think it is just reflective of a double entry in the wiki, and a misplacement.
