Cable recording issues
« am: Dezember 15, 2011, 12:20:00 Nachmittag »
I got issues with cable recordings, in normal situation I use Sundtek as C tuner only for one cable channel and many many times, recordings hasn't work properly.

1. it has recorded maybe 10minutes from start
2. recording is just blackscreen and it stops immediately after trying to play it.
3. Record is pixelated, lot´s of glitches.

All Cable channels which I use are FTA channels, so it is not any CAM issue.
I have also used C-tuner channels as alternativate services for satellite channels and looks like when VU+ DUO has recorded from C-tuner issues are there.

i haven´t tested not so much the issues, but looks like live TV wathing with Sundtek stick is Ok. All DVB-S2 works perfectly even if there is many recordings at the same time.

Read/Write troughput from VU+ to NAS (so it is not network transfer issue):
Results for write throughput:
76.695 Mbit/s with udp,async,wsize=16384
76.695 Mbit/s with tcp,async,wsize=4096

Dev. drivers updated couple of days a go and it is tested with both Sundtek Pro sticks which i do have and image is now BH 1.6.6

Will powered USB hub give some advantages?

PS. Same message (only shorter) is in BH forum, so you can ignore it from there.
