> My pvr-150s will not record in stereo, exactly the same issue as here: http://www.gossamer-threads.com/lists/ivtv/devel/37436 He resolved it by getting the kernel source and modifying the ivtv driver, but I don't know HOW he did it?

> I am using Mythdora 5 (Fedora 8), with 2 pvr-150s, and an HVR-1800 (not in use yet) which is running on kernel 2.6.24.4-64. Mono recording and all other functions are working fine.  I had this same issue before under Mythdora 4 and resolved by changing the workaround bit in the ivtv driver and remaking it, but that was with an older kernel version here: http://www.mythdora.com/?q=node/1999

> My current efforts with MD5 are detailed here:http://www.mythdora.com/?q=node/3943 Basically I installed the kernel-devel package, modified the ivtv-driver.c file to disable the pvr-150 workaround, and attempted to build a new kernel using this guide: http://fedoraproject.org/wiki/Docs/CustomKernel#Building_a_Kernel_from_the_src_RPM    Although it booted without working video, there was no difference in the sound's output, yet I found that
