No, this TV does not have hidden PVR to activate. Maybe in future we find out, but no success yet.

I was able to activate some of PVR/TimeShift menus on C550 via patching CAppUtil::FlagSupportRecordingSpec and similar functions in exeDSP memory. PVR does not work at all.
Function CPVRWrapper::GetDevTotal returns zero recording devices. So I assume that we don't have necessary hardware (or at least code to work with it) on Trident C550 models to use PVR/TimeShift. And comparing exeDSP of C650 with ours - we don't have necessary functions like formatting to XFS for PVR.
So I think that it is impossible to "turn PVR on" in Trident C550 devices via simple ways. It may be possible to make it working via adding code to exeDSP (for example via hooking tuner data decoded by the second MIPS CPU), but this would be really impossible as we don't have specifications for this hardware: http://www.tridentmicro.com/producttree ... dtv-pro-sx

I'm talking about Trident-based C550. MStar-based have different exeDSP and I never looked into it.

So, obviously, MStar C550 have the same limitations as trident has, and you can't enable PVR there too.
Is there any special requirement for usb hdd? NTFS is ok? Or should I use fat32 or ext3?
Just for information: PVR requires XFS-formatted device. And C550 does not have XFS fiesystem support in kernel.

So we could recompile kernel with XFS support, or just using XFS modules might shows the magic...

No. exeDSP does not have necessary code. And nowhere to take it from. Maybe when Samsung would release D-series TVs on Trident we would be able to steal code from there.

I download samygo ext. precompiled for T-MSX5DEUC and I found file
/SamyGO\lib\modules\2.6.28.10\kernel\fs\xfs\xfs.ko
Just for information: PVR requires XFS-formatted device. And C550 does not have XFS fiesystem support in kernel.
After insmod xfs.ko and enabled PVR on service/hotel menu, will PVR work?
with xfs formated USB disk?

p.s.
I read forum and know about HW limitation, I have another PVR device, but...

None has tried this way. Do it and tell us about the result :-)

Ok, insmode xfs.ko make nothing,
REC button on remote control make nothing.

LExxC5xx is without PVR REC.
