Hello I use VDR a few years, but lately I changed my system into ITX (AMD Brazos) and so changed PCI DVB-S2 card into USB. Additionaly I has bought DVB-T tuner. While buying hardware I was sure I buy hardware which is supported in-kernel, so no need to hunt for driver. Unfortunatelly every from three card I have doesn't work properly.
The first: Terratec Cinergy S2 USB HD. Kernel has drivers, but only for the first revision. Second revision which I have need a patch. Patch is even on linux-media http://patchwork.linuxtv.org/patch/10294/ , but isn't finished so no hope to have it in kernel soon. Anyway I have applied it's modified version from http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653026 to kernel 3.2 and it's almost work. Almost, because sometimes recording becames unplayable. Recording recors eveything, but I can play only some part of file from beginning. The rest is unplayable.
Looking for something widely used I choosed Pinnacle PCTV SAT HDTV 452E PRO USB. Problems with it i've described in thread: "[PATCH, RFC] STB0899 signal strength (pctv452e, others too?)"
The last miss was buying USB DVB-T stick based on Af9015. Generally it works, but only a few minutes. I suspect it overheats...
So I ask: if somebody has one of cards above working, please give me a note with which kernel and with which driver it does work.
Also I wold welcome advice, which from those rather cheap USB cards works without any problems on stock linux kernel.

Ps. Now I'm so desperated that I've installed 2.6 kernel and I will try Liplianin driver with it. Hovewer having 2.6 and 3.2 kernels installed together I don't know how to tell dkms to build only for 2.6 (in 3.x Liplianin kernel will not compile)
