After quite some puzzling I found out that my Digital Devices CineS2 card (a DVB-S2 satellite reception card) does not like my passively cooled (Sparkle) GT430:
The above combination has been tested on three systems (2x Intel and 1x AMD based), and it is clear:
Conclusion: The CineS2 card is nearly unusable alongside this GT430 card.
Solution:
1 - Use the CineS2 in combination with the Integrated Graphics from the Intel Celeron G1610 (HD2500) and remove the GT430
2 - Use the GT430 card for all content, and remove the CineS2 to a backend system
Actually I don't prefer to use a seperate system as backend, so hence my question:
Will I see a loss in picture quality when I switch from the GT430 to the integrated HD2500? Since loads of satellite channels come in 1080i, or whatever other exotic interlaced resolution, I want the best deinterlacing possible. I know that VDPAU is perfectly intergrated in XBMC, interlacing works flawless. But how is VAAPI hardware deinterlacing at the moment? Is hardware deinterlacing through VAAPI on the HD2500 even comparable to VDPAU on the GT430? Does the HD2500 actually even *do* hardware deinterlacing under linux?
The above combination has been tested on three systems (2x Intel and 1x AMD based), and it is clear:
- If the GT430 is active alongside the CineS2, tuner 1 has a *lot* of problems receiving quite some channels
- Tuner 2 is not affected
- If the GT430 is physically installed but *not active*, disabled or enabled in windows device manager - doesn't matter, and the iGPU is active - no problems at all.
- If the iGPU (HD2500 from the Celeron G1610) is active, but Nvida CUVID is selected for hardware deinterlacing (LAV filters) - problems are back again
- Linux or Windows - doesn't matter
