Is anyone else having continuity problems with the S660? causing rare
glitching on SD content, and glitching on HD content very often.
Turning on the `disable_rc_polling' parameter for the dvb_usb module
seems to help, but it's hard to tell for sure. Turning on the
`dvb_demux_tscheck' parameter for the dvb_core module shows continuity
counter errors every few seconds in the syslog, along with a peculiar
callback ratelimit line before each set of continuity counter errors.
Interestingly, the `expected' value is one away from the `got' value,
doubtful it's just by chance?
Here is a sample from the syslog:
[51302.316543] TEI detected. PID=0x1c79 data1=0xfc
[51302.316547] TS packet counter mismatch. PID=0x1c79 expected 0xd got 0xc
[51302.316550] TEI detected. PID=0x7b6 data1=0xa7
[51302.316552] TS packet counter mismatch. PID=0x7b6 expected 0x2 got 0x8
[51302.316555] TEI detected. PID=0x1e4 data1=0xe1
[51302.316558] TEI detected. PID=0x1324 data1=0xd3
[51302.316561] TS packet counter mismatch. PID=0x1324 expected 0xb got 0x0
[51302.316564] TS packet counter mismatch. PID=0x1c2c expected 0x0 got 0xf
[51302.316567] TS packet counter mismatch. PID=0x1f09 expected 0xc got 0xe
[51307.329040] __ratelimit: 397 callbacks suppressed
[51307.329044] TS packet counter mismatch. PID=0xfaf expected 0x1 got 0x0
[51307.339404] TS packet counter mismatch. PID=0x3fe expected 0x7 got 0x6
[51307.362671] TS packet counter mismatch. PID=0xfaf expected 0x1 got 0x0
[51307.367882] TS packet counter mismatch. PID=0x3fd expected 0x4 got 0x3
The bitrate is about 40 or 50Mbps, depending on what transponder is
tuned. This is reported by the dvbcore driver in the syslog when the
`dvb_demux_speedcheck' parameter is turned on.
I've also experienced input lag, the computer locking up for a second or
few, seemed to be during tuning. This seems similar to something that
was reported by someone on this list in the past. Disabling RC polling
seems to have helped with that.
I'm using hts-tvheadend, and it reports continuity errors sometimes as
well (though not as often as the driver does in the syslog). The
frontend is XBMC on another computer, connected via wired ethernet.
The S660 is connected directly via USB to a MacbookPro (Nvidia MCP79
chipset). The computer is running Debian sid 32bit (2.6.32-5-686) with
s2-liplianin from yesterday, and the firmware from the
100315_Beta_linux_tevii_ds3000.rar drivers from tevii.com. I've also
tried running with the drivers from that rar, to no avail.
Everything works well (no glitching) in Windows 7 x64 with the `DVB-HD
2020100830.rar' drivers from tevii.com
Is this some sort of timing issue? an issue with the USB bus being
overloaded? (I've tried removing most of the usb modules, including
ohci_hcd, hid, etc). How can I troubleshoot which driver is at fault?
Is this a firmware issue? Can new firmware be extracted from the
20100830 Windows driver? How?
Any help/suggestions appreciated.
Thanks :)
