I'd like to support you, too with testing myTV with PVR250 USB2 and/or the new Hauppauge Nova-T USB2 DVB-T card as soon as it is available (mid february).
Just for your info yesterday I downloaded and compiled the latest CVS and I found it much more stable than previous version. (I'm focused on MY TV)
Good results are:
Configuration.exe now retain double card configuration, in MY TV I can switch from ANALOG to DIGITAL card and viceversa (in WMR9 renderless mode) with Cyberlink filters, timeshifting and recording works well with both cards (but digital card is slower starting timeshifting).
Problem found:
I can't watch a program on one card while the other card is recording, in timeshifting (using MCE remote) when I press << MP returns everytime to the beginning of the file while >> works fine, when I exit from standby (S3 mode) TV preview window (or fullscreen) is black and I need to stop and start TV to reenable, real WMR9 fullscren does not work (black screen).
I'd like to help in the "My TV : BDA DVB-T" section.
I have a brand new "KWorld XPERT DVB-T PCI" card
which is not running yet in MP, installed it yesterday and
did not have the time to get it running.
Let me know if I can help.... HTPC System is currently
AMD 1.4 with 768 MB Ram on a Shuttle mainboard.
I can help you testing.
I`ve 3 different Hardwaresystems on WinXP Pro and Win MCE 2005 with
[DVB-S] SkyStar2, Hauppauge Nexus-S (Premium), TechnoTrend TT-PCline (budget) and
[Analog] an old Hauppauge WinTV/FM-PCI.
