[ivtv-users] No stereo on PVR-150 (workaround bit?) revisited

[harwood31 harwood31]

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
ivtv files had changed via md5sum output so I've pretty sure I was changing the correct files.

I think I just need to learn how to build my own ivtv driver, but now that its merged into the kernel, its seems way more complicated.  Can anyone please help me through the necessary steps to resolve this?
