A DVB-C PCI card produced by KNC1 based on the Philips SAA7146.
As far as I know all revisions should work on Linux.
Details
The card has a CI connector (Cineview module add-on required) and it works fine on Linux. Tested CAMs:
| Type | HW/SW version | Application version | Results |
|---|---|---|---|
| Mascom Alphacrypt (full) | Official firmware 3.09 (flashable) | Kaffeine MythTV |
Working fine |
The card uses the budget-av driver in Linux.
MythTV finds two tuners on this card. SD recordings hardly impact the CPU utilization. Viewing or recording (non encrypted) HD content uses about 80% of my CPU capacity. (CPU Type?)
Kaffeine 1.0-svn3 works fine. Searching for channels worked after trying different "sources" (eg de-Muenchen) in the device settings dialoge of Kaffeine. HD video did not work propperly at first, but after altering the buffer in the file .kde/share/apps/kaffeine/xine-config it worked.
Search the lines
# engine.buffers.audio_num_buffers:230 # engine.buffers.video_num_buffers:500
and replace them by
engine.buffers.audio_num_buffers:300 engine.buffers.video_num_buffers:1800
The first line modifies the buffer of digital radio (DAB). While viewing HD-channels with Kaffeine the CPU-usage amounts up to 70% of one of 8 CPUs of a Core i7 920.
