Freeze sometimes when switching to DVB-T channel

[finbarr]

Hi there. I sometimes see the Vu Duo freezes when switching from a satellite channel to a HD DVB-T channel. I am using the Sony PlayTV, and I have installed the dib0700 driver from feeds.


root@vuduo:/var/volatile/log# opkg list_installed | grep 0700
enigma2-plugin-drivers-dvb-usb-dib0700 - 1.0-r6
firmware-dvb-usb-dib0700-1.20 - 1.0-r0
kernel-module-dvb-usb-dib0700 - 3.1.1-r2.13
root@vuduo:/var/volatile/log#

A crash file does not get produced in ~/logs/, instead, I just get the VIX spinner. When I ssh into the box, I can see this at the end of /var/log/messages

I've tried doing a re-flash, and turned ON and OFF 'Send 5v to active antenna' in the tuner config, but this happens on both.

I'd say it happens on average, around twice a week (maybe 10% of the time).

Appreciate any help with this. Thanks!

I used to have a Duo with a Nova-T WinTV stick (also uses DIB0700 driver). If you're using permanent time shift to a USB device then turn it off. I had less problems with the Duo DTT when nothing else was using USB. However, I think the Duo USB channel in general is underpowered - I had constant problems with DTT channels glitching/breaking up

I've since switched to a GigaBlue Quad with 2 x DTT (one of them the same Nova-T stick) and haven't had a single glitch.

Oh now that's interesting! I do have permanent Timeshift turned on, but to the hard drive, not USB.

I wonder can I turn that off on selective channels only. E.g off for terrestrial but on for satellite channels.

Actually, I'll turn on time shift delay to ten seconds to give it more time. I'll see if that fixes it. Thanks again.

Sadly you can't.
When I was using a Duo, increasing the time before PTS started helped massively with the same issue, using a Nova-T & HDD for PTS.
Set it to start after 1 minute & see if it helps.
If so, you can probably go back to about 10 or 20 seconds.
