Multi-Tuner problem

[cmills6]

Having a problem getting my Adaptec Videoh USB & Pinnacle PCTV Deluxe USB to co-exist.
Configured as follows
Adaptec Videoh - Capture Card #1 - Internal Tuner - XMLTV.
PCTV Deluxe - Capture Card #2 - Internal Tuner - XMLTV.
Both TV Tuners work on their own but if configured as above or vice versa i get the following error "cannot connect to GB-PVR Recording Service" when the Adaptec is busy recording & i try to view Live TV on the PCTV Deluxe.

Both capture sources need to have the XMLTV EPG source registered against them, otherwise GB-PVR will think that only one tuner has these channels available.

I have configured both Tuners to use the same XMLTV file - didn't work.
Then tried to rename them as XMLTV1.xml & XMLTV2.xml - one for each Tuner & configured in Capture Sources as follows:
Adaptec Videoh to XMLTV1.xml,
PCTV Deluxe to XMLTV2.xml & still got the same error.

I have a Videoh usb 2 card and although the video plays fine, neither it (nor mpegs captured using it) will play any audio through the MVP (with either hauppauge software or GB-PVR) - have you found a way around this ?
