Thanks both!

I don't know how wide is the stream, but it could be a USB wide
limitation. My board is a little ION based and I have some USB
devices:

$ lsusb
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 006: ID 0a12:0001 Cambridge Silicon Radio, Ltd
Bluetooth Dongle (HCI mode)
Bus 002 Device 005: ID 04fc:05d8 Sunplus Technology Co., Ltd Wireless
keyboard/mouse
Bus 002 Device 004: ID 0471:0815 Philips (or NXP) eHome Infrared Receiver
Bus 002 Device 003: ID 9022:d660 TeVii Technology Ltd. DVB-S2 S660
Bus 002 Device 002: ID 05e3:0606 Genesys Logic, Inc. USB 2.0 Hub /
D-Link DUB-H4 USB 2.0 Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 1b80:e399 Afatech
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The problematic twin device is the "Afatech" one, there is an DVB-S2
USB tuner, a bluetooth dongle, a IR receiver and a wireless
mouse/keybord receiver.

Now I am at work, I will try to disconnect all devices and try with
just the DVB-T device.

I use to try with MythTV if it works or not. Is there any other tool
to test and debug more deep about USB or DVB wide?

I apreciate your help. Thanks and best regards.
