Erratic Live-TV tuning. WinTV T-500

[vfrvulcan]

Been having an issue for a long time with Live-TV tuning.

Most of the time when loading PVRX2.exe, slecting TV Guide and then a program to watch results in a no-signal error. Changing channels makes no difference. If I quit and then restart PVRX2.exe and select a channel to watch it may work.

I've just been through a session of loading, selecting a channel to watch, no-signal, quit, re-load over 20 times before it would lock on to a channel. Usually it'll lock within 3 or 4 attempts.

If I remove the T-500 tuners from the config and use just the HVR-1300 then I have no problems whatsoever. I have it configured to use the HVR-1300 as the 1st recording card due to its reliabililty and have put-up with the T-500 being intermittent. Most recordings will also fail with the same problem if the HVR-1300 is already recording.

I've had this issue ever since moving to 64-bit windows, whether Vista64 or my current Win7-7201x64. Drivers are the latest WinTV7 CD1.1b.

It'd be nice if I could just fire-up PVRX2.exe and start watching immediately but I get the feeling this is something to do with the T-500 being a hybrid USB-PCI card. As a side issue the card is not detected correctly on every boot, sometimes its found as a 'DT-FW firmware downloader'. Whenever this happens I re-boot to ensure its detecting correctly before I start using the machine.

Logs attached, hopefully someone will be able to shed some light.

If you have only had this problem since moving to 64-bit windows then it sounds like a problem with the 64-bit drivers not initialising properly.

If it worked ok on 32bit can you not move back to 32-bit?

I seem to recall that there was a problem with some Novat-500's whereby one of the tuners packed up and several people got them replaced by Hauppague.

The card does need a good clean signal, preferably direct from the aerial. I used to get some no-signal errors when using a powered splitter. Now I use a Y connector into the tuner card to accept the aerial signal and then sent the signal over to the TV.

Has anyone else reported problems running 64-bit over at the hauppague forum?
