WinTV HVR 4400 No DVB-T Channels in XP, but fine in Windows 7

[Andrew_Sharrad]

Hi all,

I'm running a dual boot system with XP SP3 and Win7.

I use XP SP3 most days so this is the one I'd like to have working.

I've upgraded from an HVR1700 to HVR4400 to get DVB-S2. The HVR1700 was working just fine previously on DVB-T.

I've uninstalled HVR 1700 including software and drivers, and then installed the 4400. It completes the tuning process and finds DVB-S2 just fine, but before that it wont find DVB-T channels - nothing found.

If I boot into Windows 7 64bit the card finds DVB-T and DVB-S2 channels.

What I've tried:
- Uninstalling again, using HCWCLEAR, and trying to reinstall
- Tried the beta drivers linked to on this forum - 1_48_29019_hcw85bda_INF.zip
- Tried uninstalling, manually clearing out registry entries and files etc.

I'm sure there must be something left over from my old install - the HVR 1700 - or even the one previous to that which was a NOVA-T PCI (legacy).

I have a second PC running XP still with a HVR1700 and that still gets a signal just fine, so I know my aerial is good.

I've included a copy of the standard logs from the XP boot.

Appreciate any help you can give,

Thanks,

Andrew

Hi,

Just to add I've tried ScanChannelsBDA_UK and this doesnt pick up any DVB-T channels either. The signal monitoring utility always shows no signal.

Thanks.

Hiya,

Finally fixed this issue, very strange - but here we go - I'll post this information as hopefully it may help someone else sometime.

I found that lots of the Windows BDA and other codec files (psisrndr.ax and bdaplugin.ax for example) in c:\windows\system32 being of 2004 date. The correct versions are 2008.

It looks like the wintv installer v7 upgrades some files (for example msdvbnp.ax and psisdecd.dll) but doesnt check all of them. The upgrade (it prompts you to allow repairing of these files when installing) must break something, or introduce versions of these files that are incompatible with each other - i.e. some old files and some new files - thats the only way I can explain the old wintv version 6 working.

Solution: Dont bother trying to replace these files manually as Windows file protection will overwrite them. You can try replacing the version of the files in c:\windows\system32\dllcache and driverstore, and then replace the versions in c:\windows\system32 in safemode, but tbh its not work the hassle.

Instead, reinstall SP3 for XP (just the service pack - I used the full download version) as this puts back all of the right drive files and codecs and bits as contained in sp3.cab. I didnt even have to reinstall wintv afterwards, everything is working fine.

P.S. I'd previously tried sfc /scannow and sfc /purgecache to try and replace corrupt or incorrect driver files and it promptly put the old versions back again (thanks m$), I really dont know how this problem started but can only assume its something to do with my wintv nova-t pci > wintv 6 > wintv v7 upgrade route.
